I recently ordered a Sawstop PCS 1.75HP TS and have a question concerning mobile bases. I'd like 4 swiveling casters to allow for more flexibility moving the TS around if needed (vs the parallel park-style base with 2 fixed & 2 swiveling casters). Two bases I'm considering are the Sawstop Industrial Mobile Base (runs $378) and the Grizzly T31566 Bear Crawl All Swivel ($109). I've noticed reviewers touting that the Sawstop base sits flush on the ground when not used. By comparison, the Grizzly T31566 rests on 4 feet. The main question I have is whether the difference between the two has an effect on stability? Is it really worth the extra $269 to have the TS cabinet rest solidly on the floor vs feet? The hydraulic lift mechanism is surely a bonus and is alluring but, I'm just not sure the extra cost for resting on the cabinet base/floor vs feet is worthwhile? Any thoughts?
