Whatever I end up with it absolutely has to be mobile. my one car garage isnt big enough for a stationary tool
Ok, here are my observations of my Ridgid TS3650/60 (I can't remember which.) It is heavy, mine weighs in about 400 lbs. Even with the lifting mechanism you don't want cracks in the floor. Once it is settled, it is rock solid. I used a plastic table saw once, never again. I was cutting a piece of 1/2" chip board and the thing tipped over. Not so with the Ridgid. I ran a piece of 3/4" plywood through, it didn't budge. Controls are handy and I especially like the left tilt blade and being able to move the on-off switch from one side to the other.
The cast iron extensions are a must. They are slotted so you can clamp feather boards and some jigs directly to the extensions. They are also precisely machined to match the table so the working surface appears totally flat. I bet if I took a micrometer to it, I could find some differences but not enough for me to care. I'm working in wood after all.
This thing is a real pain to assemble. However, unlike my bandsaw, no modifications were necessary. Assemble it alone and follow the manual precisely. Check off each step. They are not intuitive and it is easy to miss a step. But, make sure you have some extra muscle available to stand it up. I did mine alone. I stuck some 4x4s under the legs and pushed down. I just kept piling 4x4s until I had it about a foot off the ground. Planted the legs and jammed some 2x4s between them and the wall and pushed her up the rest of the way. Once she was up, she wasn't going anywhere.
The most important aspect of this class of saw is the adjustability. You can lock these things down as precisely as you want. All of the adjustments are there. The mitre slot is your point of reference and everything moves from that. You can adjust the blade to it, the fence to it, and the list goes on. I found the Ridgid precisely aligned right out of the box. No tweaking necessary.
If your shop floor is defect-free, you can setup the saw anywhere. However, I've seen some fellow's shops and flat is a luxury. The stand is particularly loose fitting. But I found that I could "adjust" the stand to compensate for some of the defects in the floor and still keep the table top plumb.
Just some meanderings.
