As for the legality - then Maine really needs to re-do its unrestricted species list. Based on your Maine.gov site, they are illegal - I would definitely check with them first, to be on the safe side.
I don't mean to upstage your thread - just don't want a fellow MFK to get in hot water.
Scott Crowe has them for $35 (Floridas) - They are about 10 or 12 inches. If you want one, I'm happy to orchestrate a delivery/pickup with you, for small compensation, or a trade.
