Hi 3206dave,
I haven't had any personal dealings with this supplier. So I just did a few background checks and its seems the site is pretty NEW, seeing that it was registered just last 1-May-09. With this info alone you should already be cautious about buying from them.
Plus they only accept wire or bank transfers again not a very good sign. There will be no way of getting your money back in case something goes wrong.
Also you might want to try getting a certificate of authenticity from them, proving that the products they are selling are indeed authentic, since they are listing quite a number of branded electronics.
With that said do be careful in case you decide to proceed in dealing with this one.
Cheers! :)
