rufio: Do you e-Bay? A decent compressor can be found there, if you do a little homework. I bought one for $45 (USD) from a "surplus/salvage" place. It was returned to the store because one of the plastic covers over the gage was missing...works just fine! Replaced the plastic cover for $2.
I personally like the compressors with a small tank (2 or 3 gallon) that give you a continuous, non-pulsing air source.
Congrats on your purchase...my Badger 155 just arrived today, can't wait to use it. (Got the flu, maybe tomorrow)
