Thanks for the replies, realize it 's a bit of a rambling topic.
Jay, you are spot on in replacing "good stuff" with things I want to collect. Funny hobby with that paradox, with a smallish number of people overall, then you layer on your specific interest and your art budgets and what's available, and you're left looking for proverbial unicorns in some cases. And then it becomes a personal preference of how you want to engage in the hobby.
I go back and forth between waiting to see what each new auction brings, debating whether to reach out to people on CAF, posting wants here...I've had success and failures at all. I probably won't attend more cons, but the idea of finding something not listed for sale or auction at a FMV is tough...but it's happened even for what I consider a modest budget and pretty popular tastes.
Certainly keeps it interesting.
