I look at this as a long, LONG-term hobby. I am willing to trade my time for money.
For example, I badly wanted an Atari Flashback 2, but I was unwilling to buy one on eBay. It took me about 10 or 12 years to find one in a thrift shop, but now I have it!
To give another, non-gaming example, there was a series of 12 (history) books that I wanted. The publisher went bankrupt towards the end, and the last few volumes in the series are extremely hard to find due to low print-runs. A few local used bookstores have complete sets, and they charge whatever the market will bear.
Over the course of more than a decade (and visiting multiple thrift stores in two cities) I assembled the whole set -- one or two volumes at a time. I never paid more than $5 for any one volume, and sometimes much less.
I will continue to (slowly) search for magazines and, hopefully, find something that I will be able to contribute.
