I use a 1/4 in 18 gauge stapler, it can use up to 1 1/2 " staples. I use it for frames and supers, with a little glue. I got mine from CPO outlet near Atlanta. They have reconditioned and new, mine was new but in an open box. Every thing was there, it is an Hitachi, can't remember exactly but was around $65. Good luck with what ever you choose.
