Welcome to the forum. Here's what I would do if I were you. E bay will give you a low end idea if you can find one on there and that may take some time. It's a great place to buy but a lousy place to sell. I'd wait for a bit and see what some of the members here say over the next few days on price. If you stick around and contribute to the forum for a while you can sell it here. That may be a better way to go but you can't do it till you have real posts, 20 of them. We have had a recent rash of 10 character posts for the required 20 posts in a grand total of 25 minutes and then bang, a for sale post.
Hop over to member introductions and post there. That will give you one more real post you need. Give it some time and see what the guys here know about them. We have a lot of really knowledgeable folks on here.
