What's the best SFC for the money and how hard is it to install? I've seen some that need to be welded, others are bolt on.

They're all basically the same, with the majority being weld on, and some being bolt on. I would go with the weld on sfc's as you don't get "bolt hole elongation", and it's a stiffer install. If you have a convertible, do some research because some will not fit convertibles. Most bolt on's can also be welded.
