To introduce myself, and a couple questions.....................

For my models, I use http://scalehobbyist.com/

For airbrushes I use chicagoairbrushsupply.com

As far as service, http://spruebrothers.com/ and http://michtoy.com/ are hard to beat/.

Well if you want to use acrylics for airbrushing, you can't go wrong with Tamiya. Especially for German armor. They have most of your needs covered.

" As far as online service for a hobby shop goes, in my limited expereince, Sprue Brothers is hard to beat."..............

I would have to agree, I recently did a small order with them, and pleasantly surprised!! So.....I dropped them a line today, and they "will" have some 1/25 "Tamiya".

Guess that's the way I'll go...........Now, for some painting tips......................

Dont forget the Academy clonesof the Tamiya Panther and Jagdpanther. I believe those are still failrly easy to find online.

And welcome aboard. ;-)

There are also some newer, and very nice models in 1/16th scale. More expensive than the 1/24 or 1/25 scale old kits but you get what you pay for.

Unfortunately, there are only a handful of 1/25 kits: a Cernturion, a Chieftain a Tiger, a T34, an Su 100, a Panther,  and a Jagdpanther, all by Tamiya and all dating back to the 1970's. There may be one or two repops of these kits. You can find them at Lucky Model. http://www.luckymodel.com/ .I didn't see then at Sprue Brothers or Squadron. 

If you have a local hobby store that deals with Stevens International, they should be able to order the T34, Tiger and Chieftain since they are listed as in stock.
