I bought a Harbor Freight compressor, about like this one
There's also 92575 and 60637 that seem to be about the same thing.
Budget and space permitting, HF has 67696 on sale $130.
That's not a very good HF sale price. At that price I'd look at Home Depot. They sell a Porter-Cable compressor with those specs along with a 16-gauge brad nailer, bag and safety glasses for around $150.
Our little HF 92575 CAN inflate our RV tires to their sidewall rating of 80PSI but it's a hike. To pick up 5PSI, say 70 to 75, takes a VERY long time even with the regulator two-blocked at 100PSI. But it fits the space we have for it and does many other projects very well. Car tires at 35PSI work wonderfully, and so do any bike tires. We have a boat trailer that calls for 50PSI and I think that's really the comfortable limit for 92575. I just bought HF's combination Tacker/Stapler 18-gauge and it operates that beautifully. Together, those two have given me a very nice Nailer/Compressor combo, with a Compressor that can do more, for around $75 total.
EDIT: Remember, for simply Inflating, you can choose (guess what?) an Inflator. It's basically the Compressor-Only part, no Tank, so you save space.
