...are there any good reliable suppliers from HK?
I'm not sure they're in HK, but you could try heli-fever.com. They have good prices and I've ordered from them before several times. There was one occasion where I didn't receive a cheap heatsink ($1.50) and when I asked about it, I never received a reply email. But I still order from them once in a while.
You need to use the forum for communicating with the staff, they always fix any problems. I highly recommend these guys, the only thing I don't like is that their stock becomes sold out very quickly so you have to be fast. They usually dispatch in 24 hours.
