I have to say the A1200, merely because of the number of hours I've dedicated to mine.
I've always wanted to own a CD32 and an A3000, and thanks to eBay, the former is on its way to me :-D
(So far I have 2 x A1200, CD32 Spectacular Voyage pack, A600 all boxed. Trying to get one of every Amiga model)
/editi: clarification
