thanks everybody, sorry forgot to ask the warranty for it.
In China now it's still not on sale, just saw someone bought GSA-20L(same with GSA-4166B) in Singapore IT Show at 109 S$ =545RMB, I believe in China it will be around 500RMB also, nevertheless, most of the time, we have only one year warranty....think should ask again 4164B, 4167B price, these two styles we have same retail version at shop/market.
You know I saw a tip
GSA 4166b.... Woo Hoo !
remi1au, LG DVD Burner
very envy for the service, that's why I want to check the price/warranty difference.
To tell you something, I bought a new GWA-4166B bulk version at 280RMB in Jan.2006, now flashed to GSA-4166B, and now join you:D
