I'm done testing these things, and they are working well.
I've written the GPRS code for them and also released a new Meitricks (Now Mustack) Android app supporting them, so they're ready to go.
I asked about getting a custom batch done (own logo etc), but that's 100 minimum - nahhhh not yet.
I'm ready to pull the trigger on importing a small batch - probably 10 for now.
So let me know if you want one. I'll throw the rest on ebay or something for a slightly higher price to cover the fees.
Mustangtech price will be $150 - this is around $100 cheaper than the price we could get for the Meitrack 3G and should cover me if I get stung for GST on the way in.
They are about 2/3 the size of the Meitrack devices and seem to be a nice little unit.
