I have the same compressor SteveU has but I ordered it "custom"? with a 60 gallon tank for space reasons. No big deal though, It is still a great machine. Pricey? Yes, but well worth it and far superior to the average sears or home depot unit. The single stage 5hp uses the 7.5hp pump and slows it down big time so it is quiet and a true workhorse. Installed probably around 4 years ago with out any problems.
As doslocos said, they are heavy. Mine was around 650lbs shipped but it still took three guys and an interesting 2x4 frame setup with an engine crane and a floor jack to get it unloaded off the pallets.
I would not hesitate to buy one again. In fact, when it was being unloaded off the truck the paint got scraped and eaton sent us a container of touch up paint for no charge. THe only problem I have had is the water drain ball valve started to leak a little bit of air, so for around 12$ I got a new ball valve, extension and an elbow to route the stream of water where I would like. Could have warrantied it, but not worth the time. When I ordered, I spoked Directly to Matt Cain, the owner of the company about the unit they would put together to meet my needs. Excellent service.
