I looked at both sites. If this is the compressor you are talking about from HF: Link it has an Italian aluminum pump that I am not particularly fond of. There seems to be a lot of cheap aluminum pumps coming out of Italy for some reason. Some are decent, others garbage. Chinook pumps are usually good, but Balma pumps are iffy. I think the US General one is a Balma. I am not sure which CH you are looking at, but the one listed as a 7HP is nowhere near that much. 7 HP is a bogus figure, since no such electrical motor exists, at least in the 10 years or so I have been working with compressors. Same goes for 6hp, 4.5hp and 6.5hp, more marketing jiggery-pokery. The 7.5 hp Campbell Hausfeld for sale at Grizzley is indeed a real 7.5 hp unit however, and it is a good pump. The 7hp "4 cycle" is a 4 cylinder single stage compressor. It is a good pump, but not a two stage. If I was looking to buy a good compressor for a decent price, I would try to locate a Quincy dealer in your area and price out one of their QT series compressors. It is Quincy's lighter duty line of machines, but every bit as good as the name implies. I imagine there is a brand of gun that is universally regarded as being the best, or very near the best. Well, Quincy is that for compressors.
