How 'bout the RWS350 in .22 - $300 at midsouthshooterssupply.com?
Accordign to straightshooters.com, the 350 has the power advantage over both the RWS 48/52/54 series and the R9 (by quite a bit).
The R9 looks to be more like a medium powered rifle, and personally I'm a bit iffy when it comes to the sliding-compression tube type breach as found on the 48/52/54. Not as safe as a breakbarrel.
