Tell ya what,I had my sights set on the ruger 10-22 heavy barrel with built in suppressor now that suppressors are legal in minn,sure is a dandy .22,but my cheap ass decided to go quiet loads and hang on to my $1200's they wanted for the ruger,not to mention being on the ATF radar for having a suppressed rifle.Not sure about other states but minnesota gun laws suck.
Further depending on what your motive is for a critter rifle,cci also offers "ultra/sub sonic" round,little more horse power than quiet loads but under 1140fps sound barrier,so no .22lr crack.

Ive yet to find a springer I enjoy shooting. If you are serious about air guns Id suggest looking at PCP's, but you arent going to find one for $100, subsonic 22lr out of a bolt action is a good alternative
Gee Lycan,thanx for the headsup,never herd of PCP air rifles,not that I would purchase one but was curious,up to $2k for top of the line 30 shots on one air fill,serious looking air rifles,bet they are loud as well like a springer.
