I believe shockers are a great way to get back into the game man. They can be wicked fast guns, and amazingly dependable with after game maintenance and cleanings. You take care of a shocker and you'll never regret owning one. Once you spend some more time with it, you can start adding different things onto it. Bolts, regs, boards, barrels, feednecks and whatever else you can imagine.
Like most people in this thread have already said, it comes down to appearances and social hype on specific guns. Most basic SFT/NXT shockers are cheaper to begin with, once you get into the Dynasty's, Nasty's, Dark's and so forth the prices rise. Shop around and make an effort to get what you want. Because it's always nice to have what you like.
