Yeah, SIMM RAM (if that's what you're using) is so utterly expensive it's not evern funny. If you look at it from a certain angle, you could say that you're buying an antique. ;-) Maybe that's why it's so expensive. :-)

There are some other programs that will work much faster than LimeWire. (I'm surprised you could even get to work on yours! Many others have not had this success.) Xolox is very fast, and it is very easy to use.
