Paint opinions ?

I use Tamiya exclusively and darn the small color range! I've had tip dry problems with MM Acryl, and the others aren't available locally.

I have heard excellent things about Vallejo and Gunze Sangyo Mr. Hobby (which I also understand is capable of being mixed with Tamiya).

Tamiya is pretty good for German Armor and Aircraft and Japanese everything. I'll probably order in some Gunze one day. 

The latest issue of FSM has some information on various acrylic paint brands. I haven't read it yet, but it looks useful after a quick glance.

My personal favorites are Tamiya and Polly Scale acrylics. 

Although I use Vallejo, which as was already stated, it is not as readily available, so I would recommend using Tamiya.

If you don't mind the online ordering process from www.ausfwerks.com try the vallejo, they're hands down the best product on the market!

This of course is my opinion!

I also prefer Tamiya but why not try a few brands and see what you personally like? 

I use mainly Tamiya paints because they flow very nicely through mu airbrush.  Many people say that they can't be used very well using a brush but I have gotten great results.  I have tried using Gunze Sangyo acylics and I think they behave much like Tamiya paints.  I have little experiance with Polly Scale and Vajelo acyrics so I can't comment on them.  I have only gotten one color of MM acrylic to actually flow through my airbrush.  Other than that, not much success with them.
