The trouble is - here in the UK at least - there is a lot of absolute rubbish being sold on the likes of eBay for ridiculously inflated prices in the name of "vintage". Low-end Technics/JVC/Marantz integrated amps from big-box store stack systems, for example, invariably alongside speakers with plastic baffles, hard-wired cables, and drivers with shiny chrome-effect dust caps. These are no match for modern budget equipment. It was crap in the 80s and it is crap now. And this stuff is generally what floods the market.
If someone I know asks me to help them build a budget-priced system, vintage stuff probably wouldn't cross my mind.
There are of course some wonderful bits of kit available from the 80s and it's my favourite era

, but you have to be prepared to pay what might feel like over the odds for it. It's a heart over head purchase which is fine for folk like us.
Mind you my Sony 530ES only cost me £120 and, well, we all know how good Sony's ES stuff is. It's my pride and joy and you'll have to prise it from my dead hands.
It doesn't help that you jammy sods over in the States seem to have readily available supplies of high end vintage stuff for about $0.005 from thrift stores and the likes. All we get is the cast-off black plastic crap with spring clip speaker terminals
Mind you, our car boot sales (known as flea markets over there) are often a good place for a bargain. I picked up a mid-range Sony CD player from the late 90s for £8 just this weekend
