We deal direct with the factory. For a competitor to sell at that price with shipping (as it has a battery included shipping is not cheap) they are definitely making a loss. -So seems like they are doing it as a way to build up their e-mail list + obviously they are obviously hoping to sell a large quantity so they can minimize the costs. Anyway, buying elsewhere means you will not get product support.
you might deal with the factory direct, but you're not based in China, probably don't speak Mandarin, and you don't have the buying power that Fasttech does. they won't be making a loss on these, FT is a giant - they don't need the custom that a few dozen emulators will net them.
FT support is excellent btw. they refund return shipping costs on failed units, and occasionally don't even require you to return the product at all in order to get a full refund.
$75 is just greedy, either that or the factory is ripping you off.
