Thanks for all the additional comments.
I spoke to the Service Manager before shipping, and he never mentioned that they were backed up. If he had, I may have tried to find a different place to send it. I should have asked, let me remember that lesson.
Unfortunately, there are only so many authorized Tascam repair facilities and the warranty time period is now up.
This situation reminds me of how many places now expect a tip for just doing the job they are paid to do.
