I couldn't have said it better myself Robert.
I started building my stash because when I put off buying a few kits I seen on the shelf, thinking I'll get them next week, they were gone forever. I too plan on building models in my golden years. Heck, at 48 I'm falling apart quick and have to plan for those sit down activities.
At first I was keeping track of my kits in a notebook. That became difficult real quick.
When I started ordering stock for my hobby shop I also created a database for my personal stash. I just add the info in a customized form. If I need to see for example what Corvettes I have I just run a report. I have a few reports already created for different subjects. I also have tables for different items such as paints and tools, etc... all including item numbers, prices the whole nine yards.
I'm even working on putting a version of the list on my web site, kind of a wish list for friends and family. One for me and one for my son.
Humm... am I an addict or a collector?
I'm classified as a recovering alchoholic, I take lots of doctor prescribed drugs to make me feel better, but I can walk past a model kit and leave it on the shelf. So I wonder....!
