Thanks for the comments guys - in answer to various questions, at the moment the only ones on display are the Space Police I sets, the rest have been broken down and packed away. I usually go through various phases and display one theme at a time depending on what tickles my fancy. With SP3 coming out I thought I'd display the SP1 sets until they arrive. I'd say about 95% of these sets have been acquired in the last 12 months. Space has always been my favourite theme with Lego so I'm eagerly awaiting SP3. Although I'd wish that Lego went back to creating themes that all crossover with each other like how the Blacktrons were going up against the Futurons, SP, M:Trons and Ice Planet, Spyrius was stealing tech from the Unitrons and the Exploriens were up against the UFOs and Insectoids. The themes now all seem to be going at it alone. Mars Mission seems to be taking place in another reality to SP3 for example. But regardless, as long as its space, I'm happy.
