Use a 12"x12" glass, had used for years in model room in Texas, when we moved here to central Kentucky 4+ years ago, built a 12'x12' "hobby room" in farthest corner of the garage.  Went to a local "flea-market-mall", got a couple of used tables.  The shorter one 2'x4' had a THICK formica (sp?) top in good shape, so decided to use it for the main building table.  When I laid my chunk of glass down on it, found no "wobble"......  dig out a feeler gauge set, and only found one small area toward an edge that could get a .002" under the glass.....  SO.....  when building a frame (etc.), sometimes use my glass, sometimes not.....    I got lucky (for $14)
