Since these threads live forever in the archive and re-emerge periodically as references, I'll throw in my bit for the Holland Exogrid.
I can't say enough great things about Holland Cycles, Holland exogrids, and Bill Holland. He and his small crew are friendly, sincere, extraordinarily talented, and they work fast. Bikes are planned, finished and delivered in 6 months, max, and that's only in the case of idiosyncratic builds like mine was.
A small circle of local artisans and mechanics build and assemble almost everything that goes on the bike, from the fork to the frame to the custom seatpost batteries for electronic drivetrains. The level of vertical integration is impressive for an operation that makes perhaps 50-100 bikes per year.
The defining trait of these bikes is their ride quality. Holland can build you a Cannondale-style crit weapon if you want, but it's still going to ride better than anything in that class. My exogrid was ordered with 1" chainstays, 42+mm downtube, and a short wheelbase, but it still rode better over all surfaces than my previous skinny-stayed Litespeed.
Exogrid test bikes are on hand at the shop, and Bill has lent them out for days to prospective customers (I kept one for almost a week before I finalized), so you can ride and experience this ride quality for yourself before you plan and pay for your bike. Anyone skeptical of mixed material frames should ride one of these before reaching a conclusion.
If money is an issue, keep saving- these bikes are worth it. Put everything into the frame spec, upgrade the parts over time, and you won't regret it.http://www.flickr.com/photos/mechanicalman/11030531233/
