I have not personally used this supplier and I'm not too familiar either. After a quick background check, I couldn't find anything negative about them and they have been online since 2004. Although they are not registered with www.bbbonline.org
They seem legit. They are using escrow as their payments processor, I am a bit concerned that they only mentioned wire transfer as the means for sending your payment. Plus the fact that they do require a hefty minimum dollar amount of $2000.
I suggest trying to contact the supplier, engage communication and exchange of information so you can get to know them better. At the same you can have your concerns addressed and check on their response rate too.
Hope this helps a bit. Cheers :)
