Tower hobbys has this one listed as late August release.
They also have some others listed that I've not heard anything about, other than Towers site.
76 Ford custom van "Phanton", 69 Hurst Olds Cutlass, 75 Gremlin, and a few more.
I use mine quite often. Very useful tool. Picked mine up for cheep at Harbor freight. The magnifying glass comes in handy as well.
I would say you should get it. I have a T- bucket frame on a clothespin clamped on the allagator clips for drying as I speak.
if you must use the propel, heres a tip; set the can of propel in a pan of hot tap water while you spray. This helps keep the pressure up inside the can.
As you use the propel, it starts to build-up frost around the top of the can, this frosting reduses pressure in the can, and your airbrush will just be spitting paint.
Just do yourself a favor, and invest in a compressor if you plan on doing much airbrushing.
