no chinese OEM repsonds asap. it's somewhat cultural and somewhat the nature of being a factory. wit-color, as do the other builders, have distributors that buy containers full of these printers at a time. wit-color has a mexican, brazilian, russian, and more. and then a guy like us calls and says "hey can i have one pritner sent to such and such?" it's like calling roland because you want to buy a printer. you have to email these companies about four or five times before they take you seriously. then you will get all kinds of stuff back and forth over the next several days.
send me your email address. i think i have some brochures, maybe a doc file with some prices etc.
i can't promise that china is the best option. you'll need to accept that you won't have a large user base, parts will be shipped from distributors abroad, etc. but the chinese machines, just this year, have started to look like they are serious pieces of equipment. that wasn't true even three years ago.
