WTB simple signal/function generator [UK]

[AudioGimmer]

Does anyone have a simple/cheap function generator for sale?

My old RS unit just died, (and whilst I will eventually  get round to fixing it) I need to get on with some other things in the meantime.

I’m mostly interested in audio frequency, so no need for super high bandwidth [ the old one was 1 or 2 MHz at most]

Thanks
