i run them all the time, my favorite 7018. ac/dc+, don't obsess on keeping them moisture free. you're probably not doing any code work. i have them on a shelf in an open can and i keep ten lbs 3/32 and ten pounds 1/8th on the truck with no ill effects. if you learn to run 7018 and 6011 you'll be up for most stick welding work.
