A Japanese girl I know is visiting here and she brought us back a few items from over there. Among those items were 2 ST starships, the USS Prometheus and a Ferengi Marauder. They are about 4 inches long each. They are part of a collection of about a dozen ships, such as the TOS Ent, the Ent-D, the Nebula, etc. Both models are extremely well-made and very well detailed and painted. The only catch is that they come in nondescript boxes and you never now which ship you'll get. For instance if you buy 5 boxes you may end up with 2 Ent-D, 2 Marauders and a JH Attack Ship.
They are available through HLJ : http://www.hlj.com/scripts/hljpage.cgi?FRT20561
