I'm more into Blacktron II
though right now my 20 some figures are without a space craft.
Er.... Lots of my instructions were demolished as a kid and I think my starguider landrover set came from the thrift store when I was younger. I built the 3 wheel tyrex, but I don't think I ever owned it, and I built a super Nova II... Thanks to peeron I tried to fill in the gaps of my collection kinda. Most the sets came out when I was 2~3 years old.
I also have a bag of parts for the Ariel Intruder. But am missing lots of peices about 50 or so for that project. I'll probably get them off bricklink
The main goal is to eventually build one of those huge blacktron space ships.
