I recommend a .36 because the largerballs are easier to handle and it provides a little more power and fun factor. It's like shooting a .22 magnum instead of a .22 LR. Plus you can just about shoot it all daywithlight 777powder loads.
Here's a discontinued but economical .36 Bobcatthat you would be lucky to find still being available for salesince CVA has stopped making them.

Or try calling Deer Creek Products, Waldron, Indiana at 765-525-6181. They bought all of the remaining CVA inventory and also sell Traditions guns and kits, andjust may have an economically priced.32 Deerhunter, CVA squirrel rifle or similiar models in kit form.
Good luck and let us know what you get.
