I think Daniel's idea of separate pieces is a good one. Buy it all if you want or buy any part of it. If you have the room to display all of it great! If this doesn't agree with you then buy one or more to your liking. Each piece need to have a reasonable price so when the each piece goes together you don't have a $240 puzzle like Navesink. A lower edition size would also be nice but only serialize one piece and have the other pieces as an add on bought directly from HL like the adapters for the lighted pieces. This will allow HL to control their own inventory and only buy the accessory pieces as their stock get low.

This sounds great, probably won't work and this is why I'm still working and not independently wealthly.
