Have a think about all the bouncing around and all the banging and crashing a DMD might cop during its trip from overseas. Thats what i would worry about.

My maths says one from Mark C for $199 plus postage is a better option, espescially for warranty etc, Imagine having to pay the postage to send something back to the USA if it came not working or broken etc,and the crap you would go through with a USA supplier, 50 emails etc etc.  Just buy it locally. Easier in the long run.
