This hobby has gone down the crapper in recent years, gone are the good old days when nobody cared about "retro".
These days, even if I (very rarely) find something of interest in a flea-market, the seller asks for an insane price (because its retro!) and quotes Ebay prices.
I collect computers and consoles since the 90's and my entire collection cost me less than it would cost to buy a single A1200 on ebay these days.
I'm not kidding.
I'm lucky if I add an item to my collection once a year, will never ever pay the ridiculous prices asked for now!
