A 12 X 12 granite floor tile works for me as a poor man's surface
plate. About five bucks at a discount floor tile place. That's big
enough for a full sheet of wet-or-dry paper so it can be used also
for truing flat surfaces.
Usual disclaimers, I don't know how flat it actually is but it's a
heck of a lot better than anything else laying around my bench and
has survived much abuse without chipping or cracking. It's stiffer
and tougher than an equivalent piece of glass.
Just for what it's worth,
