I will most likely be chastised for saying this, but here goes...get a 10/22. If I recall from your posts, you like to tinker with guns, so even though it will probably not shoot as well as the marlin out of the box, they can be made to shoot. In addition to a squirrel slaying machine, it is a great platform for 22 cal falling plates, plinking, etc. Plus, it's a 10/22, so they is plethora of aftermarket parts, and who doesn't like tricking out there guns?
Just my 0.02, take it or leave it.
