I was just doing my usual bargain hunting in various classifieds, and found the following at Airguns of Arizona's Used Section:
RWS 350 Magnum, .22 cal, "EX Condition" $239
RWS Mod. 240 Schutze, .22* cal, "LN Condition," $109 *[Typo? Is the Schutze actually offered in .22?]
Beeman HW97, .177 cal, "LN Condition," $495 another in "EX Condition," also .177, $395
BSA SuperTEN Mk 2 w/ moderator, .22 cal, "VG Condition" $495
Air Arms TX200 HC (Beech), .22 cal, "EX Condition," $395
Theoben Evolution Walnut Sporter, .22 cal, "LN Condition" $595
There's also a few other BSA guns (Sportsman HV and a couple Meteors) that I don't know anything about, so if you're interested you'll have to go check those prices out yourself; I'm not posting a price if I don't have a clue whether it's actually a decent one. Same goes for a couple Falcon FN-19's.
That said, I'm still unsure on whether some of those prices really are all that good. Mainly it was just the two RWS guns, especially the 350, that caught my eye.
