Stopped in at iMakr, the "World's largest store selling 3D printers" tonight while on business in London.
Took a few quick pics and threw them up - thought people might be interested:

I met the owner and we talked shop for a bit. He was inspired by the MAKE 3D Printer Guide to open a shop. They sell printers (I saw them sell one and talked to the excited new owner) and also do print-on-demand.
