I haven't seen this kit in a very long time. However, I have found an alternative.
A few years back, a company called Toy Island created an almost passable Endo. About the same time, Horizon created a 1/4 scale bust that could replace the awful Toy Island version head.
A decent 1/4 scale T2 could be built from these if the Argonauts kit is not available. The Horizon T2 bust and the TI Endo show up at various toy shows and on ebay occasionally.
