They have been stored in my heated/air conditioned home--not in a damp basement, hot attic or unheated garage, so they should be good to go. The third deck is a dual bay JVC that is beat up from mobile use (recording wedding speeches and conferences), so I wouldn't even try to give it away. Once I run the Carvers through their paces, I'll figure out pricing. Where are you? so I can figure out accurate shipping costs.
