First let me thank everyone for their input, it really helped me make my decision.
Dill, Old Rodie, you're absolutley right the seat is only 350 and the powder coating as well isn't too expensive which is why I decided to go with the Big Bore.
Being that the big bore is more expensive I decided that I should probably do that while I have the money to play with. The other two I can do with my regular paychecks. And besides, the big bore will be really fun, much more so than the other two.
