The one I use is a 150PSI 4 GALLON Pancake style from Sears.. They no longer carry exactly the one I have but do carry one much like it, (Different tank size as I recall) this does a great job of topping off my 22.5's and yesterday did a great job of blowing assorted debris out of my bread maker. and dust out of one of my DVR's of which I'm rightly proud (The dvrs that is) and in the past has dusted my Freezer and several other jobs.. Blows paint and stain well too.
IN short, a very nice huffer puffer.
Oh, it even picks up the motor home (12 ton air/hydraulic jack from Harbor Freight).
There are less expensive ones (HF now sells 150 PSI models) but .. Well, i've had a number of cheap compressors.. Not a one lasted a year, this Crafstnan I got in 2006 and as I said, used it yesterday.
