British and enjoying some ales? May I suggest a Samuel Smith Imperial Stout? Don't live in England, but it's imported from there, and I have yet to try a dark beer that's better. Some are about on par (like Trappist ales from Belgium), but none better.
Edit: For brews that I can get locally, here's a few:
Old Rasputin Imperial Stout (not as good as the one made by Samuel Smith, but much more readily available, as it's brewed in California)
Pretty much anything from Sierra Nevada. Pale Ale, Stout, Porter, they're all good.
8 Ball Stout
Old Engine Oil
And a bunch of stuff I can't remember. The problem with craft brews is you usually get one bottle of each when you're trying out new things, and it's hard to remember what the good stuff was called, especially if you keep on drinking.
Oh, and for some decent cheap beers you can get around here, my favorites are Yuengling Black and Tan (which runs about the same price as Bud Light but actually tastes halfway decent), and Killian's Irish Red (which is not actually Irish, but is delicious and only slightly more expensive than the Yuengling.) It's also hard to go wrong with anything made by Sam Adams, but it's one of those things that you can get anywhere and isn't as good as the actual craft brews but is more expensive than the cheap stuff, so I don't often buy it.
