Define Deep v?
I got a quote for a set of 1340g 30mm custom wheelset with white ind. hubs for about $730. The problem comes when you look deeper you almost always end up with carbon rims, which bumps the price up to a $1200-1300 starting point.
let me know if you find anything...

I sporting a set of new training wheels from Neuvation http://www.neuvationcycling.com/wheels.html
Very sturdy...and they always have deals...
I've got about 400 miles on them...not one complaint.

Off the shelf the Rolf Prima series on sale would be in your price range.

Check out Mike Garcia's website: www.oddsandendos.com
He can hand build a very reasonably priced wheelset. The niobium rims he has get 30mm deep or more.

what about Mavic cxp-33's? Put them on an Ultegra hub and you good to go...

I have a pair of Rolf Prima Vectors on my roadie. 30mm "deep" bladed spokes. Nice wheels, no issues. I also have a pair of Bontrager Aero Selects on my tri bike. 30mm, standard spokes, no problems. I dont know if I would spend the money on a pair of 30mm wheels unless they were ultralight racing wheels. They arent so much more aero that they are worth the $700 when you can get good speed from a 50 or 60mm carbon deep V set for a little more. Get a cheap set of training wheels for $150 and a nicer set of light race wheels for the big days.

Performance's Titan wheels are supposedly pretty good- and CHEAP-

Formula gets mixed reviews. I had a set of formula MTB wheels that lasted me untill i gave the bike away- but you cant beat the price, tho the Fortes MAY be better quality

I dunno if these are any good- but they are cheap.

A little more, but solid spec-

Dont worry about weight when it comes to training wheels. In fact, the more spokes and weight the better. When you switch to your light wheels for racing, its like taking off the E brake and you will appreciate those light wheels that much more.

These wheels are AWESOME!!

I train with them and race with them and have not had to true, grease, or fix a thing on either wheel for over 2,000 miles. They are priced very well and are FAST!!
Be sure to check them out before purchasing another wheel set!

For value and sturdyness, the Neuvations are great. I have two sets of training wheels. CXP33's and the M28Aeros.

Nothing wrong with either, but my CXP33's are getting long in the tooth.

The Neuvations are inexpensive and I have not had one issue in over 2000 miles.

See Anton's post above for the link.

I'm both a happy and frustrated bonty user. My training wheels, bontrager race clnchers are bomb proof. Theyhave about 2500 mile on them and I haven't done a lick of service.

But I also had a set of x-lite tubulars with the flangess dt 240 hubs. I stomped down on the drive side pedal taking off from a stop light and pulled 2 spokes through the hub body. The wheels had only 400 mi so there was hardly any stress put on them. Sent them in for warranty and 6 moths later I still don't have anything in hand. And since they require you to go through a network dealer for all warranty issues, they are near impossible to follow up on. And now my shop went out of busness, so I need to go to a trek store to try to follow up. Highly annoying.

I can't really give you a recommendation on the rear hubs since I trashed mine (but it was the bontrager design, not DT), but I have them on my Aeolus 6.5 front wheel and my x-lite front and they are as good as any I've run. But these are both primarily race wheels and have only a few hundred miles on them each, so I don't know too much regarding durability.

I checked the specs of the 1850's and they seem ridiculously heavy for what they are. If you're a big rider and put out a lot of power, they'd be decent for racing Tris, but better as training wheels. Plus, I don't think they have the specific 240 hubs (which run about $500 alone for a set), but I could be wrong on that. If you're looking for a solid, 30 mm aluminum rim with fast hubs for racing tris, especially hilly ones, I'd recommend Reynolds Solitudes. You can find them for pretty cheap - around $400 - and all the kinks have been worked out from the previous model (Alta Race). They are also nearly a pound lighter than the 1850's and the hubs are just as fast as the 240's (use the same hubs as the Alta Race, and Assault). They are also pretty durable. I put a few k miles on my Alta Races last year and they're still smooth as the day I got 'em.
