There is probably room for a TC channel, but who knows if anyone will watch it or not.
The casual observers get a surprised look on their face when they see the inside of mine whether they asked to see the inside or are simply walking by. Probably, some of the rest of you get the same. I always get ... I didn't know they were so big inside. Frankly, most people haven't thought about a TC as being something that is possible.
There are definitely "old fashioned" models that are still being made. I don't think many models with slides fit in that mold.
