if you find me one and I buy it I'll give you $100. sound fair?
the requirements are:
-at least 48" wide up to 72" wide, at least 96" long up to 120" or so
-needs to have some sort of grooves or scribe lines on the top to locate/measure from.
-height is not super important as that can change pretty easily... 18" to 36" or so seems common
-around $1000 or under
-closer to south eastern michigan the better
-you find it and I buy it, I'll give you $100
