I'd honestly avoid MDG dice until they begin engraving the legends.
I picked up a set of their Jasper dice and numbers were peeling off the D20 after a few months of once-a-week sessions, being rolled on a felt-lined table.
andrewdcatowait...what? I bought 6 sets of their dice, and they are inked(or painted on, if you prefer calling it that), and aside from a d10's ink being slightly...dotty(as in a few numbers were not completely filled in) they were excellent quality. How, exactly, would the numbers peel...?
