Watch for import duty and VAT.
Don't want to rain on your parade, but you will have to watch out for import duty and VAT when it is shipped to you. Also as the unit is coming from china, check whether the manual is in English etc.
Not sure about their paymant system, only Bank of China wire transfer or Western Union? I'd never use Western Union due to lack of comeback if anything went wrong. As for Bamk of China, I'd be very careful......
EDIT: My apologies, just saw they do take credit cards. Comments re. Import duty and VAT stand.
