Just FYI, I agree with SpenceG. A mint condition R10 sold on Ebay for $375 and new R9's can be had from Pyramyd Air for $399.
Probably less when a sale happens.
For the R10, $375-$450 seems realistic. Guys will spend a few more Hundo's and now your in PCP territory, and once there you probably wont look back at spring guns. At least that was my experience..
That said, if you are only gonna have one air rifle, that R10 would be a great choice. Parts are still widely available for them also..
