You'll have to decide which way you want to go. You're gonna get lots of different opinions which way is best, but you'll have to decide that on your own based on your abilities, wallet, tools, and just which one you like the best.
S-10, M-II, Camaro clip, they're all here. Take a look and let us know which you decide.
