I'm in the same boat. There are simply not enough shelves in my space. When my friends come over and they marvel at the size of the MOTU collection on display, they all make suggestions as to where yet ANOTHER shelf could be put up. I've considered putting my least favorites in a box and packed away, but that seems unfortunate. I'm a completist in some rights, but I will have to make some difficult decisions this year when it comes time for any other large-scale beasts. I am just truly out of room.
