If you don't know about this place, you have been living under a rock.
I have bought from this site so many times I've lost count. Matt's prices are competitive and he's one of the most honest dealers I've dealt with. I have bought from him and have sold to him. I always enjoy doing business with this site.
If you plan to sale anything to him, he will low-ball you. It's understandable that he needs to make a profit.
I've had one deal take a few weeks before he finally got it delivered. But that was years ago when he was working by hiself and he was swamped with orders.
