I also echo Seau's comments. I have the original Big Block, red and white. Since then they've changed the rear fork ends a bit and they added the signed seat collar. I really like the looks of that. Mine doesn't get ridden as much as it deserves, but it is fast, fun and absolutely beautiful.
The one knock on these frames is that they put the bottle bosses on the seat tube. It isn't a big deal to me but I can understand the issue some have with it.

I would love to have one of their geared bike framesets but they are currently beyond what I want to spend. I keep hoping to find one gently used, but so far, no luck.

P.S. Forgot to mention another thing they do to all of their bikes and that is treat the inside with a corrosion-resistant coating. That helps preserve the frame and eliminates the need to use frame saver.
