There are plenty of 'dumb' MIDI keyboards around, but you'll usually need a USB MIDI controller for them to work. PM for my phone number, Pip, if you want a chat - or maybe I'll see you at the Sarries session on New Year's Day (lunchtime onwards)?

You're probably going to find what you want in 'Cash Converters' or suchlike - I've found all sorts of bargains in my local one - such as a Burns Double Six electric 12-string, a Tascam 788 digital recorder and a few PCs.

Off topic for a moment - the reason why PCs seem to end up in there cheaply is because they're riddled with malware! Forewarned is forearmed!
