I haven't heard a lot good about Banana Hobby... best bet for VSTank is Toyeast.com. I've ordered some of the small VSTank *R models. from them. Reasonable and quick shipping direct from China
Google "Banana Hobby Reviews" and read the responses.
Also, if you are interested in airsoft models you won't find them at a local hobby shop. Only the IR models are sold in the US. That is one reason I went with the 1/16 scale when I got into this hobby. A local shop for me carries the IR models but they are more expensive than you can get from Toyeast.com
