So here is the deal. I currently own a cookshack 009 electric smoker. Purchased it last year used and have loved it so far. I now have the itch for a charcoal smoker. I came across this WSM, my only concern is what appears to be rust on the grates and some rust on the top exhaust vent. Not sure if this is going to be something that can be resolved. Thoughts? do you think its ok for the price?
