do you know anyone who has recently moved? i'd go with recomendations before anything else.
another thing- you can use either an conveyencing firm or a solicitor. when i looked around, there was a big difference in price. i went witht he convenycing firm, because they had online access and were in the middle of the range price wise. for comparison, i bought a small 3-bed in midlands. without stamp duty, i paid a total of £2,289 (this includes all searches, fees, money transfer fees ($-£))
