Watch the "super coupons" and the 3-gal compressors are $40. I'm on my second one. They're fine for occasional use, but the piston "ring" is a little ring made of some kind of fabric. It's a "100-PSI" compressor, but I'm glad I only inflate our rear duals to 75 and the fronts less. Compressor does well on car and small trailer tires, up to around 50-PSI. I like having a compressor available, great for toad, for bikes, OK for a few PSI to the RV tires. I get it out at home to run my HF air nailer. Then I found the RV spare was at 50-PSI. Compressor must've run 15 minutes to get the tire to 80 and next time I used it, could produce about 30-PSI max. Looks like new, just shot. But for the price I went and got another one. It's a limited-homeowner-use item. Don't give that old cast-iron twin-cylinder Craftsman in the corner of the garage away.
