Cosmicco in Hong Kong sells both 2 and 4 slots for the same price. They are both priced at $145 (the last time I check). With shipping by EMS ($55), the total is $200. And they are English boards by the way. I suggest you contact them.CarlDMC:
I've heard the same things concerning 4-slots being more reliable. But I was thinking the less I have to swap carts, the less I actually handle the mobo. I guess if I get replies strongly urging me to get a 4 versus 6....
I also found a store in Hong Kong that has a 4 and 6-slot for about $160 each, but S&H bring it up to about $240...
