I know the upgrade pain, but you can always hold on to them for parts for a basic server or donate them to a friend's computer. I'd go for the upgrade if you can afford it. You're shortchanging your system and what you can do, and memory is so cheap these days. I can remember paying almost $700 for 16 MB back in 1994! I'm seeing 2GB sticks now for as low as $33 to up to $100. So for $66 - $200 you could never see an out of memory error again for quite some time.
