IIRC they're based in Westerham (Kent, but very close to London). It's a 
pity they're mail-order only (I don't trust the postal 'service' round 
here...), as I could collect from them very easily, and I'd probably have 
bought some stuff from them if I didn't have to worry about the post...

Of course not. Making things myself seems to be the only way to get them 
even moderately well designed now.
