have you tried vinegar and baking soda mixed with boiling hot water? cheap and better than draino. the baking soda cleans really well and expands once the vinegar hits it. then boiling water finishes up the job. I do this in all my bathroom drains every couple months

All the under-sink PVC plumbing is totally clear now, but there is still some kind of blockage past that point (the metal plumbing going through the wall). I took the PVC stuff apart again yesterday when I initially posted, have an uncle dropping off a drain snake tonight.
