I hate to say it, but I think you overpayed, since I got an R500 new for under $1000 back when they had only been out a year or two. The R300 and R500 are regularly sold new and used on eBay, once in a while an R700, you can get an idea of the prices from there. A friend of mine recently got a new R700 on eBay for around $800, but that was a great deal.
