IDK, you tell me, Roland RAP-10 at the bottom of a box I already thought I was getting my $20 worth in in other stuff. Voyetra V4001/2 ditto, which box had some other gems in it also, not so pricey but hard to track down. Got a P5A-B for $5 the other year. Finally got curious about a 15+ years ago curb find that I just left in a stack, and it was an IBM BlueLightning BL3 system. Bought a Banshee for a few bucks at thrift two years ago, I think it was a $40 card then, but prices have gone higher. In general, cash outlay on most of the things I have in my stash were very little, they were lame old junk at that time years back, like 5 noteworthy Soundblasters and 4 voodoos.
I think 2024 though, I've only made some deals that were "alright" rather than astoundingly cheap, though next year I could be telling you I made out like a bandit if those things turn into high demand, high priced parts. Don't think I've got anything since 2017 that I have failed to mention on "What retro hardware did you buy today" thread unless it was really minor bits and pieces. Edit: Oh yah, best ratio 2024 pickup might have been a clean maybe new in box Geforce4 MX440 for a dollar, they're not worth a lot, but a dollar is still a small fraction of it /Edit. Actually give it 2 years some of the stuff I mentioned in the "modern" equivalent thread might be lifting off 🤣
You'll notice the stuff I am having most fun with is the weird old shitty parts though 🤣 General intention is to settle on some "good enough" configurations as well as a few superstars, and let the rest go, but I am slow as hell at it.
Edit: I guess things like the IBM PC330 6571 DX2/66 box I got for $10 the other year is listing at $200 plus on eBay now. Also I prolly only paid a few bucks in thrift for my Model M spacesaver... and all the rest of my Model Ms. (boring shape ones) Though those last mostly fall in the "long enough ago, you could fall in a pit of ewaste and shake $1000 worth in 2024 prices out of your clothes when you got home." kinda time range.
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.
