While I like most others have a shop-built DP table and fence that works extremely well for all my needs. Reading your post the precision you seem to require would make me suggest the solution "SplinterGroup" refers to. These X/Y tables were quite popular on drill presses back in the late 70's - early 80's. I have one stored away that I haven't put eyes on in almost 30 years. Looking at a 2 HP jet table saw the other day I tripped over one in tall grass just outside the owners shed. My point is that these are not so rare a commodity that you should be able to acquire one both easily and affordably. Good luck.
