Check eBay. There is the previously mentioned 1/4 scale kit, and Kaiyodo also did one in 1/6th scale. I built that kit and have photos on my website of the build: http://www.devinjpoore.com/boba.htm
There are companies that have done recasts of the 1/6th scale kit (can you recast a vinyl kit?), and I've heard that it is best to steer clear of them.
