Divorce Collection?  Good one, 1kon.  Yeah, for those more premium diecasts, it is to drool.  
Display space is always a challenge.  I like 1/72 the best, although for larger aircraft the 1/100 and smaller are blessings.  
Since can't get more than two 1/72 in a linear foot of display space, the 10 aircraft in the current Matchbox WWII Collectibles already fill a typical shelf.
And they are SUCH fun to dust.  I tell the wife to leave them alone because the dust adds historical authenticity as byproduct of unsurfaced runways.  No one but me touches those fragile models without a permit, and so far I have issued zero permits.
