Personally, with my 2 Stars with air, I just adapted a small HF 12 volt air compressor. That thing will really get out the pressure, albeit with a very small volume. But we don't need a lot of volume for bullet sizing compared to maybe filling car tires or running an air tool, so it works great. And it is much smaller, takes up no floor space, just put it on the bench. I tend to run my cylinders at 120 lbs, with just warm softer lube. It just gets too messy when heated up too much.
