So let me see if I understand. Pre-Chinese starships were offered in silver and black versions and Chinese production offered the same silver and black yielding a total of four styles? In addition, there was also a rare blue version? Was the blue one Pre-China?
LavaWorld only made 2 rockets in the US, both 32 ounce, one base was black the other silver. Now they make rockets in China but they are only 20 ounces lamps. The wire legged rocket you show is not a LavaWorld product its a knock off.
I paid $50 for a silver with a red lava yellow liquid globe in it, I only paid $50 because I wanted the lamp so bad. The lamp was in excellent condition but it did not come with a box or paper work. A few weeks later I paid $20 for 2 midnight starships both with blue liquid yellow lava globes in excellent condition without boxes and documentation. The average ebay price seems to be about $40+shipping so I would say dont pay more than $40 unless you really want the lamp.
I personally like the black starships because of the holes. On the blue/yellow lamps you can see yellow lava in the bottom and top but its green in the rest of the globe. Right now I have 2 midnights and 1 silver sitting next to each and they look great. Starships are hard to come by so I suggest you take mandy up on that offer.
