There is a nice shaving shop in Leeds, they can set you up with a nice Michael Waterhouse strop they are called The Traditional Shaving Company and also have a web site. They mostly do safety razors so very few if any stones but the shop is still well worth a visit. They do have a few straights though. Also look at theinvisibleedge.co.uk he sends things out really fast. There are lots of others, but mostly web based. These are the two places I have used and can recommend.
