I'd look for a well used cheap bass here in the UK - something you can see and try. There are deals around, as long as you're not looking for a fully pro instrument for peanuts. And it will take some time.
Local shops, colleges/teachers and "repairers" are worth a phone call, as well as free listing mags etc. I got my Czech laminate cheapy from a local guitarist who had bought it from a school. Not a great instrument, but its ok (I mainly play EUB for gigs, but if someone really wants an acoustic....). Make sure you budget for new strings, posiible new bridge/endpin....and a set up.
