I use this for airbrushing scale models. The volume is great. Setup was relatively easy, especially since I had no experience with setting up or using compressors before this (make sure to use the tape to seal the hose and prevent air leaks). Small, light, delivers up to 40 PSI as advertised. The only downside is that it tends to walk, but that isn't really much of an issue for me.
