Easiest bet is to buy it from Dell. Give them the service tag # and they'll have just the right thing to sell you. The truth is... they will probably give you a reasonable deal. Memory is just not expensive anymore.
You *will* however save a few bucks by cruising the lists... like Toms's Hardware or Craig's List. They'll have the same stuff at something of a discount.
Thanks. I'll check that out...when I'm more inclined to do so. ;-)
Gonna sign out for a while... might even be back.
Later evellybody...
