I think those 3 Hardy books are my favourites too, I agree the Well-Beloved isn't quite as good, but I think my least favourites are A Laodicean (sp?) and Desperate Remedies. But I remember quite enjoying Two on a Tower and the Trumpet Major, and Return of the Native which I re-read a couple of years ago, and his short stories are worth a read too if you fancy something shorter.
We stopped off at Dorchester for lunch on the way to Devon the other week, it's a nice little town.
