Buy My Home

My partner and i are buying a property and we have been quoted £650 for a solicitor via the estate agent ( so the solicitor is not independent). This amount is apparently fixed and if the sale does not go through we do not pay anything. I have asked around family and friends for a recommendation but everyone i know has had bad experiences with solicitors. Can anyone recommend a good conveyancing solicitor either in Bristol or in Wales and advise if this amount is a good quote, the house is £69,000 and freehold and we have no other property to sell???
