I have a 3/4yr old Aiwa mini system. It cost about £250 - goes super loud, has a pleasant array of flashing lights and other gizmos, without being too gruesome on the eye, and is grey in colour. The speakers are fairly largish. Fully working and in good nick, with no discernable imperfections. Original manual as well. Its free if you collect it. I'll even wrap/box it up for you, so that nobody catches you with it.
