The way round buying in bulk is to request a "sample unit" and like i said, negotiation is key! They initially wanted ~£185-190 (prices were in dollars) which included paypal fees and shipping. After 2-3 min of haggling, he waived the 5% paypal fee, and offered me a nice round price of $275 which equated to just under £175! the guy emailed me back and said it is ok to post his email addy: yaoxincn02 at yahoo dot com! Also Alibaba has a chat now feature like MSN - much easier to use that than sending emails back and forth!
Shipping with this guy is also fast... Was sent out on Friday Lunch, and has been sat at my local DHL depot since Sunday afternoon, so it would have arrived yesterday but it was a bank holiday! Has been loaded on a delivery truck this morning so will post details of the unit when it arrives!
