RE: low cost xy table

Depending on your requirements for a table a $300.00 one is going to be hard to achieve.  This is especially true if you need a heavy duty design.   

A simple design is to use linear guides or ball bushings and flat and parallel plate of either Al, Steel, or Cast Iron.  
You can buy Al tooling plate.  There are sources for CI tooling plate.  If you use steel and maybe able to find some finish plate.
If you could see your way to front some ball screws to manually position your table you would be ahead of the game when it come to adding the positioners.   Also a free running table requires some clamps and/or mass to stop any vibration.  

The was a site that had a picture Thomson Mill Drill free running X-Y table that would have been an excellent guide but has the site has died.   

Also I’ve seen a pretty sound table made from skate wheels, Al/steel channel and Bakelite Plate.

Checkout the surplus sites for components once you get a tentative design.

RE: low cost xy table

I don't even see a commercial X-Y plotter for less than $400: http://www.jdstest.com/catpages/xyrecord.htm

You might possibly modify an ink jet printer, which has almost all the requisite functions.

Why $300?  That seems to be a highly artificial requirement.

couple of old IBM printer carriages stacked on top of each other. Real cheap, good control but not much power.
