Willem is an open source design, it works best on Windows machines, requires a parallel port (there is a newer version of the Willem that uses USB, but most WIllems are still Parallel Port models), and it a cheap entry level programmer that requires manual switch changes to program different ROMs. To that end, I bought mine for $15+$15 S&H. It looks like they are running a bit higher now, but: http://www.ebay.com/itm/Willem-5-0-EPROM-PIC-Programmer-27C256-27C512-E10-/… Looks like a reasonable buy. While there are Linux options (http://sourceforge.net/projects/geepro/), I think you'd be better off buying a better programmer unless you enjoy tinkering with config files and such. The Windows option works well because it's a "select the ROM type, match the switch settings on the device with the picture on the UI, program" type of operation.
