As I said, what we need are numbers, and facts. We are arguing without data. It may very well be that Dynavox can't be beaten, but is can't really hurt to check into it. It's called giving luck a chance, around here at least.
A buying club doesn't have to be the importer, or deal with the factory. I don't know whom Dynavox deals with; there may be more in the middle than we think. But even in just dealing with Dynavox, there is strength in numbers. Car dealers have had to adapt to car-buying groups that go price shopping; the members save a good deal. When you buy ten or twelve cars, you get their "better than best" price right up front, and later an even better one.
Numbers, and facts. How many would some wholesaler require as a minimum order? At how much apiece? Where are they delivered? How is quality guaranteed? Can we get a mixed order, with more than one model woofer? All this sort of thing.
THEN, and only, then can we consider how many we can handle, how to handle them, how to pay for them. Also whether we'd overbuy, to later provide a source for members, and at what price, and, if so, then where and how to store them. And, who does all the work.
For my part, I will start looking in Taiwan. Anybody who has bought any of these lately and has info on the manufacturer, even just a name, please let me know. My carton is 8 years old, but I will try to find them starting from that. If I can, I'll have my Chinese friend see if they would sell a couple of hundred, and for how much, etc. The Chinese love to haggle as much as anybody
