I've got two CB rigs for Sale
but I think they might be out of your budget mate, as they are very good sets. The first one is a homebase Colt Excalibur SSB fully banded from low low to high high band with a muppet band eprom and on/off roger beep switch. This has a built in power supply. It looks like a Ham International Jumbo but in silver instead of black. £100 for that.
Second is a Magnum S9 10 metre rig, fully modded and pre ROHS, with suitable PSU. 45 watts output. £250 for that.
Both working fine and can be tested before purchase.
These rigs are not legal to use in the UK without a licence, so are for educational purposes only, of course
