Thanks all, from what I have been reading I think a compressor with a tank would be best.    So Elm city, the Harder and Steenbeck is out.

I have been looking and the Iwata smart jet does not have a tank.   But it does have a quite a few good reviews.   

I am still bouncing around on this and we will see where I go.   I really need something that can run for long extended times.

Looking at the Iwata Power jets...

Does anyone have any experience with this company:

The air brush depot brand?   I have ordered from TCP Global before and don't have a problem with them.
