Took the Plunge and Bought the Iwata HP-CS I bought an Iwata HP-CS from Art Supply Warehouse in Westminster, Ca. I also bought an External MAC Valve. When I asked about the HP-CS vs. the Revolution CR, the sales person recommended the CS as being more versatile. The CS will spray a finer line than the CR. Better for weathering and fine detailing. Both will spray the rather thick paint we use in model railroading. (Compared to ink) I will get some old cars and try it out by the weekend.
After much research I chose the Iwata HP-CH. It's more airbrush than I probably need right now but I hope I can grow into using its capabilities. I've never used an airbrush before so there's plenty of room for growth.
