I've never sold knobs, but I did sell an oven light fixture and a pair of racks. Took awhile on both, but I have ample storage. I think I sold the light for like 20-25 so netted maybe 10 after costs... racks I want to say I got 30 for, so maybe 13-14 net.
Know the oven model # for search engine hits.
You need patience, but you can make MTS on some things.
