$50-$60 normally, yes, with complete copies running a little ways into triple digits. As for gameplay, I dunno if I'd pick it up, though; the SNES one wasn't quite my cup of tea.
Btw...if you'd rather have a Japanese version of Mother 2 (Super Famicom), I have a loose cart I could part with for, like, $13 shipped...
