I have an almost brand new Hard Core Tools flooring pneumatic nailer/stapler for sale. It was used for one bedroom. It works fine. Uses air pressure from 70120 PSI and staples/nails from 1-1/2-2". Comes complete with a mallet/hammer and additional equipment in original carrying case. First $100 gets it.
Note: I also have a Senco flooring stapler listed separately. Used once.
