I had some assorted Playmates action figures of the TNG crew. I also had a toy hand phaser and tricorder (again TNG -- this would have been the early-to-mid-90s), which were nice touches when I went out for Halloween once dressed as Data.
There was also a toy version of the Enterprise-D that I owned... actually, I think I still have that somewhere. I'll have to look around for it. I remember that the nacelles came off fairly regularly (whether I wanted them to or not), but I had a good deal of fun with it.
