Re: Changing my goal for collecting?
Both options may be expensive, but I think you may find it will be more expensive to get one of every airline that had the 747 in their fleet. Would this new strategy be in 1:400, 1:200, or a mix. May want to consider what space is available for displaying unless you like rotating what you display.
For me, I have my core US carriers and ones I flew on. After that it is what I have seen or like, which after awhile I sometimes sell to keep things interesting and fresh as well as let other collectors get something they have been looking for.
