Query: Hitachi Brad Nailer

Awsome nailer. I'm glad I bought it, and even more so that I bought the factory rebuilt tool. I'm not a professional builder, just an advanced handy home owner. This tool has cut my labor time by about 75% and it's cheap. You do need an air compressor, but I had that. It's a well constructed professional grade tool that meets my needs.
