It's go some time to go yet, but for us, this Philips stereo 22AF 200 portable record player is the bargain of the moment on eBay.
A 1970s design, but quite a sophisticated one, this mains-powered player packs away into a small carry case, looking pretty cool like that too. But open it up and you can remove the sides, which double up as two speakers, offering that stereo sound on the go. There's even dual volume controls, one for each speaker.
Sold in that orange colourway, it's currently up for just £1 (plus some postage from Germany). Yes, an absolute steal. Check out the record player opened up over the page or check out full details at the eBay site.
