I have one of the $6X (they move around in price, usually $60-70) Harbor Freight compressors and it's a beast, way quicker than the cheaper ones, the one that's about $30 isn't bad either is just slower...
Depends on what you are trying to do, the big HFT compressor has been reliable for me, have a couple friends with them and they work good enough to use for going offroading, air the tires down (35" tires aired down to like 8psi) while wheeling then air up with that in about 20 minutes to about 25psi, that's all 4 tires...
