Agree, different compressors for different needs. For 18ga and 23ga pins I absolutely love my Senco PC1010. It is tiny, light, quiet, and you can fill the little 1 gallon tank with air and depending upon pin size and no leaks, I can run like 20-30 pins before it needs to top off. This is great if you need to do some remote nailing in an awkward location or are just too lazy to bust out extension cord and put it away
You can get them for $120 and for $200 get the combo with air line and 18 gauge nailer and brads I got. Seriously smoking deal. I can't tell how many thousands of brads I have shot with this thing but it keeps up like a rock star.
