Great write-up. I'm like you with your WOZ purchase. Why not wait until the kinks are worked out? I'm curious why you didn't do the same with your TH purchase? Basically, you somewhat invalidate your comparison because you are comparing an early production TH with a late edition WOZ. Nevertheless you have added to my conviction to stay my TH purchase until these types of issues become less frequent. Regarding your mech issue, that does suck. I would ask them for a replacement mech. You never know, it could fix the issue and it would eliminate a lot of other troubleshooting. At minimum, it eliminates one possible fault and you get an extra mech
