I kinda like the Rigid out of the three you picked but I waited myself and found a 3hp 220v single phase 1970’s Unisaw on Craigslist for $300.00 last year. I only upgraded the fence with a 30” Beismeyer and realigned the top to the blade (which you should do even with a “new” unit) and was total out of pocket around $575.00.
5 years ago, I found a 1990’s Craftsman 10” contractors TS on Craigslist for $10.00 with a new 1.5hp motor that the owner installed and wired wrong. Once I redid the wiring, I used it for 5+ years with excellent results.
If your not in a hurry, I would check out the deals on Craigslist, on eBay (local pick ups) and your local paper classifieds.
If you cant wait, then find the one that has the features you want / need in your price range and go for it.
Hope this helps.
