I have an Ingersol-Rand, single stage, 60 gallon, 5hp....and wish I had a larger one.
From past experience I can tell you one thing to avoid like the plague is direct drive compressors! While in the military I purchased 5 direct drive compressors, and NONE lasted more than a month.
The compressor I mentioned above will handle most of my needs, but is woefully lacking when it comes to running my blast cabinet....about a minute's worth of blasting, then I have to let the compressor catch up....it's time consuming and annoying.
If you want one that will last, make sure the actual compressor is cast iron....many of them these days are aluminum, and will blow the head gaskets in short order....worse are those that have cast iron lower sections, with aluminum heads....dissimilar materials that expand/contract at different rates, and everything leaks after a short time in service.
