I was also not sure I needed a compressor and nailers. I had done some research and decided that if I did buy, I would get the Bostitch with 3 nailer set because of the 7 yr warranty on the nailers (only 1 yr on compressor). Eventually came across a great deal and purchased. Have used the nailers a bit here and there, but don't know how I survived without the compressor. The air is great for cleaning the tools and helps after sanding but before finishing a project.
