$799 for 128MB
$849 for 256MB(there's a $10 off instantly, so $839)
$949 for 512MB(there's a $10 off instantly, so $939)
My Mac buddy recommended 512MB for when I get my iMac, though I do plan to make DVDs with it. I suspect 256MB would be more than enough for your friend.
One odd thing - there's a "double your ram for $40" - probably explains the 256 price of $839, but not the 512 price.
If you buy Office at the same time it's only $199 instead of $499.
