I've heard of them, and I've heard them. They are built about 50 miles away from me in South Wales, and a guitar shop near me has a couple in. They do a 10w and an 18w head, and they also do a modded 5w Epi amp, with a power attenuator built in - all Class A. I've tried the 5w and the 18w, and they sound lovely. Also heard them demo'd at the 2007 LGS, by a far better player than me, and they sounded nice there too.
There's plenty of excellent quality amps like them out there, but if you're a classic rock and blues man I reckon they're well worth investigating. If I remember correctly, the guy in the shop told me the 18w head and 2x12 cab was £1250 or so. Hope that helps.
