Not really surprised that anyone's suggested it yet, but there's always the Mossberg 702 plinkster. I picked mine up here in Canada for about 189.00 after tax and stuff, it'll more then likely be closer to $100.00 down your way though since everything seems to be a lot cheaper down south.
Pending on who you talk to, their pretty accurate and fun for the price. I've been able to hit a pipe a bit smaller then center mass from 100yards away and then able to hit a steel drum from 218yards both while zero'd at 25yards. I've also been able to hit pennies, quarters, nickels and cherry tomatoes from 25yards.
Only "problems" I have with it are that there's no sling mounts on it at all and I've yet to find any aftermarket stocks for them. The other "problem" is that (as far as I can tell) you can only buy 10round magazines. Other then that, I love it.
