Ooh, had loads of cheapies over the years but the cheapest was a blue 3 p/u Futurama. strat shape but with switches rather than a selector. It had a perspex/glass top to it which I suspect was to protect the dodgy vinyl over chipboard body. I paid £6 for it from an old school mate and traded it in for a Japanese LP copy in about 1974 for - guess what ? - £6! Wish I'd got it now...
