Mine's an "Alltrade," which I'm sure I got from Checker Auto. Got a regulator on it, and an auto shutoff, internal fan to cool the compressor, and came with all the hosing, nozzle-accessories, tire inflator, basketball inflator needle, blow-up doll air mattress inflator,
After about 10 years, it's finally developed a slow leak, probably the regulator diaphragm or somewhere in the fittings or hosings. I don't think it's a tank leak, with the RH so low around here, it doesn't collect much water, and it's not wetting the foam rubber I have it sitting on.
I paid $39.99 for it about ten years ago, but that was when $39.99 was $39.99. Probably about $65 in today's money.
As I said before, you can't realize how handy they are until you start using one. Just watch the spray from solvents.
