I've told you all this more than a thousand times, but my dad found my current commuter bike at a car boot sale for £10 and it had a new LX chainset (has since broken, but still), and it was a Specialized Hardrock but an older one before the frames got totally oversized. We did put on some new brakes, swapped handlebars/stem with another bike, used the rack off the bike I rode when I was about 10, and used some old mudguards I had replaced on another bike with some prettier ones and it had some tyres from the 'they won't do the touring bikes but they still have a few miles in them' plus a cheap dynamo and lights and some bright orange £1 bar tape. So far it's saved a couple of hundred quid by commuting for 8 months, and I use it for Go-Ride and short (less than 30 miles) off road rides. And if I do grow out of it it'll get a good use the squablings and it'll fit my mum too.
Non Cycling ... the £5 DIY not EMI Gaidhlig na Lasair punk CD, there's probably some others that I've forgotton.
