I've visited the Cardiff store when I uesd to live in the area (it was very useful to have an Amiga store very close). Have to say I was impressed when I found it. Lots of lovely Amiga stuff all over the place.
The guys are really helpful and gave me a hand getting the Amiga working for no additional cost. There service is superb and I can't express how nice these guys actually are.
Any Amiga project is guaranteed to have bits in it by these guys!
