I remember when I was a young college student building models in my spare time. Usually when the school was closed or not in session due to long holiday weekends. I didn't have a car and lived several hundred miles from home, so building some cheap kits was an inexpensive way to pass the time while stuck in the dorms.
As a lieutenant in Germany, I pretty much passed the time away doing the same thing in the BOQs. I had a small Badger airbrush, but often didn't have the materials or ventilation to safely use spray cans or an airbrush. I had money, but obtaining the supplies was more of a problem.
The vast majority of my kits were built out of box with whatever brush paints I had on hand. I kept a few of the small empty Testors paint thinner bottles to mix some custom colors, but for the most part, I mixed by eye. I wasn't always satisfied with the shade, but that was the best I did with what I had.
Most of the kits sat around on whatever flat surface I had in my quarters. Many of them went straight into the dumpster when I left Germany. Some of my more "prized" builds managed to make their way back to the States.
Fast forward to the 2000s, it seems like as soon as I got a new uber kit, I immediately looked for whatever photo etch was available, along with an aluminum barrel and maybe some aftermarket tracks. I built with a purpose, but it wasn't always relaxing.
Looking back the last 8 or 9 years, it seems like I am almost going back to my roots. I tend to buy the "lesser" but still new kit and forego the aftermarket. Some are contest worthy and many go onto flat surfaces in the basement on "display". Not really seen by anyone but me. Just about every model I finished was enjoyable. There were a couple I had to beat into submission in order to complete.
