I have a quincy, its a really nice compressor. Those IR units are harry homeowner compressors. Might be good enough for your needs but you get what you pay for.
You’re absolutely correct. I’ve bought and sold a lot of compressors over the years. I bought the IR from Tractor Supply and I’m going to pick it up Friday. If it’s crap I’ll let everyone know and you can say ”told you so!”
