I have a Recharge and really like it. It has a lot more built in safety features than most. It is fully self-contained and the cooling system does a good job of keeping it cool. It is based on the YH type compressor, but has automatic temperature protection, over pressure protection and run time protection. My old YH used to run right around 90C when filling bottle guns and my 90ci Guppy tank, the Recharge doesn't get hotter than about 65C. It also has an on-board oil/water filter, so you don't really need another external filter. I have been very happy with mine.
