Ok, forgive my ignorance here, but Im in the market to buy a convoy, as I must shamefully admit I still do not own a convoy figure. I was wondering what to buy, as I see there are many good looking figures available. I guess my question is: what is the difference between 20th aniv. Convoy and MP-01 and MP-04 Convoy? Also, are these figures worth the price tag? I also wanted to ask about the THS-Convoy... is this just a very small but super articulate figure? It looks very promising, but 4 inches seems so very small. If I were to go one direction, which should I get?
