I bought my 60 gal. upright from Tractor Supply a few years ago. It's dark green, and I think they called it Farm Boss or something like that. They also had the IR for a couple hundred more. Mine has given me good service, but right after I bought it, my son had something large he wanted to sandblast. The rig did the job, but I went into the shop to check on his work, and the 3/8" copper line from the compressor to the pump was glowing red. That's been several years ago, and I haven't seen it do that again. Of course, there hasn't been any need for sandblasting either.

That's why 2 stage pumps are better and more efficent. When air is compressed it creates heat which also causes condensation. A 2 stage pump can create more pressure at lower rpms with less heat and condensation because it compresses the air in two steps rather than one.
