First off, forget the PVC airlines . PVC is not approved and the shrapnel generated when it fails can cause injury or death. Do a search on PVC airlines here if you are considering it.
I bought a "Sears Best" (actually a DeVillbis) 120/240 volt belt drive 20 gallon portable compressor back in 1980, which I recently resurrected for temporary use until I get around to replacing the filter/dryer in my shop air system. The old compressor probably is roughly equivalent in air delivery to the TSC unit you're considering.
It runs air tools, a sandblasted, and has painted a few cars over the thirty years it was my primary compressor.
It works fine for impacts and air chisels, but the duty cycle is limited with cut off wheels and sandblasters. You can work around that , though.
There is no comparison to my 80 gallon IR or Champion, but there's no question the old Sears compressor met my needs for 25 years as a hobbyist
I understand the compromises a hobbyist makes when also raising a family, and suggest you go ahead with your plan to buy the PC compressor you're eyeing. If $400 is a budget limit, stick to it and don't succumb to the bigger is better syndrome.
