:]Ack! Thanks for reminding me how old my PC is.

I'm using a 2.4Ghz P4 version of the 2400, with 1GB of RAM and XP Home. It still works great, though I'd like to have another gig of memory. The price for 1 gig sticks of PC2700 is steep compared to newer stuff. I put 2 gig of PC5300 in a newer laptop recently for a whopping $15. It costs around $75 for this old 2400.
Take a look at the for sale forum here, I bought 2GB of PC3200 for around $30. PC3200 is more common and will work fine in your system even if it is at reduced speeds plus there is the chance it supports PC3200 speeds as well for some performance gain.
