1. Buy a refurbed PC with XP Pro 2.8G processor & 1G ram for $159.00 has Printer port and serial port.

2. Buy a new desktop and a PCI add-in (expansion) Parallel Port card for about 14.00 bucks

3. Buy a USB CNC driver solution for MACH (about $140.00) aka Smooth Stepper by Warp9

Laptops are poor choices for CNC controllers unless your intent is to setup your CNC machine on the kitchen table each time or make to easily portable. The PC that runs a CNC needs to be considered a dedicated Controller. It has to be optimized to run the machine. Laptops break easier and are more expensive to fix/replace. There are problems with some laptops (even with a Smooth Stepper). You may face video or other timing problems with MACH on a laptop. About the best PRO for a laptop and CNC is it runs off a battery so the Ground is via the system (more noise immune).

Check EBAY for good deals on computers that will run MACH and not bust your wallet. I have been buying nice HP's and Dells that are refurbished and ready to run. I buy 17" LCD monitor for less than 50 bucks. You do not need a Dual-Core-whiz-bang computer to run MACH (or EMC2) but it needs to be considered part of the machine if you want to be able to just fire it up and cut something.
