I don't know this supplier personally, but my advice - STAY AWAY from them. They are based in China and offering brand name electronics. So the likelihood of ending up with counterfeit products is very likely :)
Plus, they are using a free email account through yahoo, not very ideal either.
Although, they advertise PayPal as a payment option, when I tried doing a test purchase the only options presented were Western Union and Bank transfer (to Bank of China).
Hope this helps.
