Welcome and good luck. Great cars and I love it more than when I first bought mine.

As far as price -- depends on a number of factors -- like where the car is, mileage, number of owners, maintenance papers, forum member or not, etc. Lot's on the SRT6 section to look for info and pricing. As noted below, $15K may be the mid point but many variables could take it north or south of there --- including color.

Personally, I went for a NA instead of an SRT6 for a couple reason (even though I'd like to have one of both -- The IC pump is an item that would likely be an expensive repair (if I had one I'd use it), I'm not a fan of the spoiler (although it has grown on me a little more than at first), and the suspension is a little stiffer than the NA and I use mine to commute in DC and the roads are getting worse by the day and it can make for a harsher ride. While I'd certainly love the extra power, I don't need it and I expect I'll mod my NA to add a little more ponies, I'm very happy with it for what I use it for --- which is spirited cruising.

Good luck with your search and decision.
