Nice. In that case, just save up some cash and buy what you want. The only way prices are going is up.
I had a look in my eBay history, it goes back to 2013. I got my Biostar 486 board from the US, cost me USD 60, back then a hefty price, but I wanted the board and these days I could easily sell it for much more.
I got a few 386 and Super Socket 7 boards from amoretro a few years back. A bulk purchase. Look at the prices he's selling at today, must have doubled or tripled.
Today I bought 3 graphics cards for USD 170, a LOT of money, but I really wanted them, not just for my Windows 98 benchmarking program. But I also know that in a few years these cards will sell for much more, like everything else. The seller is top notch, got a lot of things from him previously. I rather give a good seller more money then cheap out and risk a dud. There was another seller, haven't bought from him before, he had a few cards but wasn't willing to combine shipping or "do a deal", and I would have spend likely even more than USD 170.
So what I'm saying is, don't wait too long in a rising market...
