Well, I'm basically doing the same thing you are. Not quite ready to take the plunge into RC, but the VSTank Pro's and Trumpeters look tempting.
VSTankPro supposedly have a Japanese Type 90 available, as per their website, but I don't actually see it for sale anywhere. That's the one I'd like to have.
Although I like the Trumpeter's larger 1/16 scale, I notice they kept the national markings off their tanks - no maltese cross for the German tanks or red stars for the Russian ones, but at least their being consistant in keeping both national symbols off.
