At those price points it will be a while. It isn't impossible but you better be quick if someone puts them up for that.
I recently sold a Mega Man 3 for $160.00, and have seen others go in this neighborhood. RC PROAM seems to be getting mroe and more rare these days. While I know one person who got one for $50.00 or so, they more commonly sell north of $100.00. Just my personal experience. Goodluck.
