Just last night I was admiring, oops, I mean organizing, my unbuilt models. I would guess I have about 100 kits of things that go fast on the ground and an equal number of things that go fast in the air. Add a couple of armor kits (I'm diversifying), a couple of ships, one dinosour, a visible woman (for my daughter), and a visible V-8 (for my other daughter), and the total just tops 200. I would guess I also have 30 or so "minor" kits - figures, support equipment, and the like. I have about 8 kits nearly finished, awaiting inspiration, four or five started but quit in disgust (either a major goof on my part or on the part of the manufacturer), and another 3 actively underway.
Yes, I would notice a rewrapped kit for Christmas. Oddly enough, when I went through my inventory last night, there were no surprises - I know every kit I have purchased. If only my memory were that good in other areas! Another observation - except for a few duplicates, almost every kit has has been unwrapped and inspected. I intend to build them all; I'm no collector.
I am just now restarting the hobby after a 4 year break. There have been some great releases in the past few years. I am still buying far faster than I am building, but I plan to have a very productive winter. So many models, so little time....
