lotta really crappy computers on craigslist. Intel Pentium M and such.
suppose that's about what I should expect for what I am looking to pay though.
Nothing wrong with a Pentium M. They aren't really "Pentiums" in the sense of "crappy old Pentium 4" that most people think of. A Pentium M would be quite capable of handling all the tasks you mentioned. The only things out there faster are going to be dual core CPUs.
