Eastern Bloc in Manchester in my preffered shop, its just packed with techno, and the guys behind the counter and Mark Turner and the legend that is John Berry. they know their stuff.

liverpool is shit really for record shopping, Xfade is new but not my sorta record shop, its shit bright, and hardly any decent underground stuff, just technos top 10 really. 3beat is shite. The best record shop in Liverpool is Probe, about as underground as it gets around these parts
