The granite one is looking good. Probably cheaper than a Regal or Dyna King base as well. I didn't see any weight specs listed on the site. I'm thinking about making the move from my Regal to a Dyna King Barracuda.

I agree. Pretty interesting way to create value from spare small pieces of granite.

looks like the sell for anywhere from 65 to 95 bucks and weigh around 4lbs. The barracuda is nice- 10/0 - 22 size hooks is nice to have. I paid about the same amount for my first car, lol!
