Yamaha DTXpress/DTXplorer/DTXtreme

Hello everyone,

i've been saving since birth and finally have enough cash to spend on 
the new DTXpress. my question is whether anybody here knows of any 
good dealers in the UK. I'm based in london but am more than willing 
to travel to save some cash. any other advice for a 1st time buyer is 
also much appretiated. 

merry xmas and all that
pete
