4jaw we use those cambell compressors like that at work for nailing mostly. I think they might be one step down.. Anyway they are really tough compressors. We have given them hell for four years and they are still fine.. However... I would like to replace one with a lightweight compressor. I get sick of picking those things up.. 40lbs I would think.. The wheels are nice, but for me at six foot five they don't touch the ground when I stand up straight.
I am going to try one of those lil HF compressors.. If I like it, I will get one for work.
Probably that one you have there Matt.
