That's quite a dilemma. I suggest sending it to me why you mull over your options

Semi-Seriously, I am torn - The value will go down slightly once it's assembled and used, but then it's like restored muscle cars (or classic or antique) we call trailer queens (hauled from show to show, never driven, never allowed to be trouched) - what's the sense of having a classic if you aren't going to enjoy it?
Build it, then set up a laser securtiy system around it, that can be deactivated by you when you want to play
IF I could find a used one, in good shape, I'd sell it and use the profit to buy the second one, and to buy something for Mrs Birdman.
