I love the Tak85. It’s a forever scope for me. I have no doubt you would really like the 106. It’s famous for a reason
HOWEVER…some thoughts
The Tak focuser has internal parts that can fail in 24-7 heat…such as in a remote observatory in the south (Mine is in Texas). Easily fixed by replacing the focuser with a Feather Touch (one is made especially for the Tak FSQ85). But then you have to add another $1.2K to the cost of the scope. If you are using it on occasion and then bringing it inside, then no issues with the factory focuser, which is also really good.
Moving up, the Takahashi TSA 120 has incredible optics, too. And guess what? It comes standard with the Feather Touch focuser (the focuser is made in Ft. Wayne, Indiana, thank you very much). I would say no one is producing a direct competitor to the TSA 120, so if you want best-in-class, this is the one (unless you want to move up to the 130).

And some other models that are so close that Takahashi can feel their breath on its behind…
The Red Ultra Cat series from WO is killer. Pretty much matches the optics of Takahashi, is more robustly built, has an internal focuser that will never flex, a nice rotator, and easy to access tilt adjustments that can be adjusted while on a target in real time. It is a Pezval and is therefore very forgiving with how the optic train is assembled…keeping tight focus over a large range. I haven’t handled an Ultra Cat yet, but I suspect it’s also a forever scope.

Lastly, Askar’s SQA line performs similarly. It’s built in a more conventional fashion and I suspect the series would make users very happy. It doesn’t come with quite the number of features as the Ultra Cat, but it fundamentally produces similar images.

My affection for the Tak is a little old-school. The crafts folks who fashion the optics are unparalleled. I enjoy rewarding their efforts. These other scopes are made in a more factory-automated way and companies have refined the process to produce optics very similar to Takahashi. As a result of the more automated construction, the prices on them are lower.
Have fun picking one. You won’t regret your choice of any of these!
