I had the same doubts. They later completed the swerve without problems (there's a video somewhere), although I don't know if they went thtough build with it.
Ballshifters work fine for the life we expect of them.
AndyMark sells the Swerve and Steer, which is basically everything you need to mechanically build a swerve drive. They were out of stock of assembled kits and shipped some unassembled, but apparently even if they were assembled you had to take them apart and reassemble due to some manufacturing errors and tolerances. Still, to the teams I talked to at champs, they were very easy to implement once you assembled them (buy a couple extra modules).
A lot of people like the Revolution swerve modules sold by team221. They are pretty light, but require you to set up the steering motors and drive motors to transfer power to the module.
If you go custom, be prepared to manufacture all the parts. Design with cost in mind and it won't cost much, but will probably need to manufacture a couple parts. Look around chief delphi; there have been many designs posted over the years.
Go to team 1640's Swerve Central wiki page to learn about their swerves and stuff. It's a great page with lots of resources.
