First off thank you for all the great advice! [smile] [smile] [smile] [smile] [smile]
That is what I love about this forum.
I wanted to post a follow-up for anyone else wondering which saw to get the TS-55 REQ or TS-75. In my case I went with the TS-55 REQ and exchanged the 55" rail for the big 3000mm rail since I already had a rail on my MFT/3. Here is what made me chose the TS-55 REQ over the TS-75.
1. Design: It became clear that Festool designed the TS-55 then added on the TS-75 to meet market demand. This is kinda like Porsche designing the 911 and then building the Cayenne SUV to meet market demand. Some of the design features that give it away are things like the splinter guard fitting perfectly on the TS-55 but on the TS-75 it is too small, or the allen key storage on the handle of the TS-55 fits the key perfectly, but on the TS-75 the blade housing is in the way, or when you bevel the saw the TS-55 is balanced but the TS-75 will fall over if not supported. I am not taking anything away from the TS-75 I am sure it is an excellent saw. It just appears to me that the TS-55 is the flagship tool from Festool's design team and the TS-75 is an addition to meet a specific market niche.
2. Use: I measured everything. 8/4 wood at the lumber yard, doors, tables, old 2x4's new 2x4's, trim, siding, copper gutters, flashing, floors, you name it. And nothing came up over 50mm thick. I am not cutting down trees, and I am sure some folks need the depth of the TS-75 for raw unfinished lumber. Not me I am firmly in the suburban handyman/homeowner category. So then it came down to power. The TS-55 should have enough power to cut 50mm but in the worst case you can always just make the cut in 2 passes with incremental depths if you feel it is getting bogged down.
In the end I went with the TS-55 REQ for the same reasons I went with Festool vs DeWalt. Bigger is not better. Better is better. A beautifully engineered tool that does 95% of your needs flawlessly is always the best option. Unless your 95% includes cutting 2.5" lumber then buy the TS-75. [wink]
