That’s an old one, I’d grab it right away for 25 bucks, I think concept 2 even still sells parts for those so you could replace your bungee, chain etc. no reason you couldn’t get some good workouts on that.
Again, for 25 bucks you have nothing to lose. My friend got one not as old as that one, for 300.00, the computer on it crapped out and concept2 sold him the upgrade computer for a great price, we went through that one and replaced all the maintenence parts. My buddy has been using it 4-5x a week for the past 5 years now.
