Compressor help--- Please

[Maxbashing]

Hi All,

I have been using an airbrush for a while using cans of compressed gas and I can't deal with it anymore so I want to buy a compressor. I am only going to be spraying shells when I need one so I am trying to do this as cheap as possible. I have found several cheap compressors but I was wondering if anyone had any thoughts or opinions. Here is a link to the one I am considering buying

But I am wondering if I NEED one that has a tank like-

I will many be spraying clear lexan bodies but I have done a couple of restorations on older Tamiya cars so might use it for that too.

Any thought/opinions/experiences would be very much appreciated.
