Kim,
Hang on to those old machines! Or get an old used one (on the web, computer shows, repair shops - they are everywhere!). You can get pentium-2,3 machines for < $100.
Set it up with Win9X and you can use the fractint you love. I can easily render 1600x1200 on my P2-300, which is 10 years old.
My P3-733 with Win98SE actually runs fractint much faster than either P4 unit.
