Have just purchased a new Sony DAV-SA30 home cinema system of ebay for £102!, which i think is a steal, as they retail for alot more??. Was in 2 minds about getting one as i have heard more than one person having problems with this model, for instance having to turn the unit completly off via the plug socket, over heating, and a increasing buzzing sound! Has anybody got one or knows someone who has one, and have no problems with it what so ever??, or are they really this bad?. Cant believe Sony would release a model onto the market that has so many faults!
