i'd go with dave's suggestion- yamaha pacifica 112v or one of the better vintages (I've tried some of the cheaper ones which I didn't really like, though that was a while ago and supposedly the quality of even their cheaper ones has improved). I've seen some good deals on some of the vintage advance models, too, on places like dv247- i think you can get the HSS strat for about £180, which has the steel block trem, locking tuners etc. Might be worth considering.
