You'll still find cheap deals.
Whenever I find someone selling a Performa (insert # here), or one of the dime-a-dozen compacts on craigslist, and they want hundreds of semolians for them, I ALWAYS send them a note saying "as a collector, I could literally put a message on one forum and have one of these for $20-$30 by the end of the day. I know you're hoping that somebody will pay you $200 for that thing, but 1) collectors like me are wise to it, and 2) anybody who's not a collector won't have that kind of money to throw away."
