We have been trying to point out that the US General compressor at HF is NOT Chinese and it is not junk. That one you have in the pics is an American built compressor except for the very good quality Italian built pump. That is a good compressor and the fact it is from HF means little as it is actually a rebadged Belaire. That US General is a good home shop outfit and is hard to beat for the money but of course the Quincy being more of an industrial type unit (and priced accordingly) is going to last longer and will have a heavier duty cycle. It all depends on the kind of service you need, if you are only looking at home shop needs the the US General will perform well and last a while but if you need full time service 8 to 10 hours a day 5 or 6 days a week then the Quincy is the obvious choice.
Also if you only need home shop service and can spend the extra money then you can count on that Quincy for many years, maybe a lifetime.
