ive had my black magic sitting out on my tv stand for a couple months now. and I've been contemplating on rebuilding it. but would it even been worth the trouble of purchasing new o-ring kits and screw kits along with anything else that needs to be replaced. because honestly, i never set it up or tuned it since I've owned it over a handful of years. it hasn't been aired up or anything since 2008. what do you guys think?
