I'd go for a Marlin 795...at this time they're selling for $100-$129,
and Marlin has a $25 rebate on 'em good until Dec, 31st, 2010
There are plenty of fun accessories for them, and even Ruger stocks can be modded slightly (10/22 is slightly wider) to fit the 795
Not to mention that the 795 is WAY more precise out of the box
