Having just completed converting an X2 over, I did a short spreadsheet to go back and figure out (roughly) what I spent. I also included links to all of the places I bought each item (Public Document):

The numbers are all rounded up to whole numbers and I got a hell of a deal on the X2 through Harbor Freight when they were running a special at $399, plus free shipping. The price is back up to the $599 mark now. I did not factor in small items like center finders, cheap dial indicators and other sub $20 items. Based on my numbers, completing the job for $2K is perfectly doable.
EDIT: The belt drive kit does not have a link because I could not find the site that I bought it at. For reference, it's the kit made by Starleper1 and the kit is phenomenal!
EDIT (Again): For software, so far I have only purchased Vectric's Cut2D for CAM at $150. I am using the free version of Mach3 since I have no need to go over the 500 line restriction at this time. I am also using the free Desault Systems software Draftsight for CAD. It's simple, but it meets my 2D drawing needs.
