My dad used to have an SA520, which was basicaly the same, but with one less button on the front and a bit less power. I remember the day he bought it home and I just loved the Pioneer logo power meters on the front! I'd never seen meters so responsive before - although I was about 10 at the time. I think he had it for about 10 years. In that time, no faults, sounded great and if you can pick it up for £50 or less it'd be a bargain! I almost bought an SA620 a few weeks ago off ebay just for old time's sake!
