OK, Tom, given your needs and budget I'm going to recommend Xenonproject.com for a Panzer III and a Jagdpanther, both airsoft, it will cost around $240 for both, including the shipping. If that sounds good you can order at www.xenonproject.com and these are the two tanks

If those don't work for you let me know and we'll see if we can find you something else.
