I could do a custom name version - like Swinks, Cow Corner etc in the Marshall font if I can find what font it is, and people pay me a small design fee but then the item but a cost only purchase price from Shapeways and I won't double dip.
Also I have written to Marshall to see if they will allow it or if they earn the margin on the Marshall Logo and not me - worth a try.
Here is a cool item - Marshall Speaker / Amp Fridge for the Games room.
