Probably go for Graphire 4

After asking for suggestion from friends, comparing the price and performance, I think I pretty much settle with getting the Wacom Graphire 4 CTE-640/S0-C Silver color 6X8 USB Tablet. With the Hong Kong price HK$1250, the tablet is pretty reasonably priced comparing with the US Price. My next question will be whether I should trade in my old tablet for HK$150.
