Don't know if its the type of animal you're looking for, but the max038 from maxim has the range/waveform you're asking and is easly available from RS.

something like this: http://www.hobbytron.net/functionsub.html ?

i think there are a bunch of $5 cheap ICs (which these kits are based on) which do exactly what you want

can't find a link but a web search should reveal more eg http://www.mitedu.freeserve.co.uk/Ci...ar/funcgen.htm

A 555 will do the job for you up to 10kHz, IIRC (been a while). 555 and 556 are dirt cheap, common and easy to wire to put out a square wave. Whether it will be clan enough fr what yu want to use it fr is another question, however.

A 555 wired for astable operation will do that. You havent said yet what you want it for, so now its probably too short
