I had an opportunity to use the TS-75 CMS insert for about a year here in Minnesota. The TS-75 part of it was great, install an appropriate blade for the task, and the saw had plenty of power. Where the TS plates falter is, unlike the CMS-OF plate that allows you to make adjustments and bit changes from above the table, the TS-plates require you to perform any and all adjustments, blade changes, etc... from underneath the table. This isn't necessarily Festool's fault, it's simply a function of mounting a handheld circular saw upside down. Depth adjustment was ok, but because of gravity PLUS the spring tension in the TS-75 wanting to retract, it could be difficult to really dial-in an accurate depth. Blade changes were a bit tedious. The deal breaker for me was setting bevels. I had to reach underneath the saw, release the front and rear locking knobs, then try to look at an upside-down bevel scale that's largely obscured, set the bevel, then try to lock the front and rear knobs without losing the bevel setting. If you're mostly just ripping stock at a zero bevel, and precision depth setting isn't a consideration, then the CMS-TS plates are a great fit, but if you need to quickly and accurately make depth or bevel adjustments you're better off looking at a Precisio or Erika saw.
At the present, the Precisio saws are NAINA, though if you do some digging there are plenty of ways to get them here. The CS50 seems like a perfect size but I worry about it being a tad underpowered. The CS70 has oodles of power, but is too large to fit in my Sprinter as I have things arranged right now.
I'm planning on picking up a Mafell Erika 70 later this year. 2200+ watts of power, 120v motor, all of the functionality of the Precisio saws, available right now in North America.
As has been stated above, I own a ton of Festool tools and appreciate every one of them, but have begun to supplement them with Mafell tools where Festool hasn't released their version in North America, where the Mafell is the superior product, or Festool simply doesn't have a comparable tool (I just got a KSS 300, LOVE IT!!).
Right now I'm using a Bosch GTS1031, it's ok for framing duties (ripping furring strips, etc....), and for cabinetry it suffices with a SHARP, high quality blade, but I'd really prefer to go with the Erika 70, just a matter of working a few extra weekends this summer to cover the premium price. BTW, for my Bosch saw, I cut the legs down so the table height matches my MFT/3 tables, making for a nice saw station!
