Again building on what Jazz has said above, depending on what your cutting and width/length of the machine you could also look at rack and pinion set up. There are some pretty good sources these days for both and I have seen a few sources for helical which has some serious benefit in resolution over standard R&P set up. I have seen one set up in the US that has an inverted rack under the table, but the designer pointed out that crude still can get on the pinion without proper shielding.
As far as the MD machine, sell it on ebay as a whole unit. I sold mine to someone who wanted to do some poking around and testing and for what he wanted with the care to keep it completely flat it does what he wants. Anyone wanting to get very into serious CNC activity I would strongly NOT suggest any of MD's smaller line as I have yet to see any product that will not end up twisting itself or otherwise creating misalignment just from running. That is my experience and opinion. -MichaelSoftware SolidWorks 2024, Onshape, Aspire v9.5, Blender
