Welcome to SaleHoo :)
I'm not that familiar with this supplier but I wouldn't buy from them for sure. I know everyone's looking for 'the supplier' of iPods (iPhones and other Apple products) but oftentimes they just end up being scammed.
Anyway, here's why I wouldn't buy from them:
1. The payment method - WIRE TRANSFER! Most legit suppliers will offer you a safer payment method or at least other options. Remember when you send money via wire there is no way of getting it back, no chargebacks, no disputes - it'll be gone just like that.
2. They have been online for less than a year, although they'll turn a year old by May 2010, this also corresponds to the expiration of their site registration. (Ideally it is best to deal with well established suppliers with at least 2 years of online activity)
3. Their phone number is a mobile phone number.
4. You can't buy just 1 unit but you have to get 10 samples. What if they are not as authentic as they claim? I respect MOQ but if I have to pay via wire transfer I would not want to pay for 10 units.
But if you'd like to give them a definite if a doubt, you can try exchanging emails/call and get to know them better. But be wary of any signs.
All the best! :)
