SourDieseL said:calling easton is one thing, dropping off a wheelset at my builder is another. i've had no problems with easton, they've sent me a brand new complete wheel on a whim with a return label for a circuit rear I had a few years back. My experience with 3 wheel builders is that they were more then willing to work with me on fixing a wheel, but ended up with more out of pocket then say sending it back to easton.
In times of need, I've had to go to my shop for last minute needs and thats fine since I know I'd be running right into the race time wise without any restrictions of say not having a set to race on. This isn't to say I do not support hand built/trued wheels, I think they are a very viable option for the OP. At times I think they are best per application and expectation.
Sounds like you've had issues picking builders. Just like an LBS, if a builder doesn't work for you, go somewhere else.
Factually, there is zero that a boutique, large manufacturer built wheel has over a custom built wheel. Zero. I had issues with a rim on a custom built wheelset that started sprouting cracks at the spoke holes. The builder replaced not only the cracked rim, but also the other rim so that I'd have a matched set (for the "repair" he used a different rim maker). It was done gratis, and he got his money from the original manufacturer. I had my wheels back toute de suite.
On the flipside, long ago when I had a set of Bontrager Race X Lite wheels, the rear DS hub flange did what was expected of Bontrager hubs at the time and it failed catastrophically. Not only did I have to wait a month to get wheels back, I had to let Bontrager determine if it really was their fault.
Unless a rider's really jonesin' for a wheeset with carbon spokes (Topolino, Lightweight, Reynolds, ADA, or at the [censored] end of the spectrum Mavic R-Sys, and so on) there is no need to get a factory built wheel. CF aero rims are readily available from Zipp, Corima, Reynolds, Edge, and others. You can get all manor of stainless steel spokes (which blow the pants off of proprietary aluminum spokes) and, if you've got an itch, Ti spokes (Pillar). The best hubs in the world are available individually (PW, DT, WI, Royce, Goldtech, Zipp, Alchemy, Ligero, CK, Campy, Shimano, Tune, PMP,...........), so I can't think of a single reason why anyone would want a boutique wheel hub (like, for example, the [censored] Mavic rear hub).
With a custom built set, you get the bonus of having a wheelset whose spoke tensions are as even as they can get and that are sufficiently high. You get the bonus of having a wheelset built to your needs (hole counts running 16............40...........whatever you need or want.)
Best of all, almost every time you can get the custom set cheaper or at least end up with more value for the money.
The only thing you might not get with custom wheels is a tacky set of stickers and a big name. That's about it.
