Hi folks...quick question...it has been a while since I have been keeping up on things here due to other issues...ut finally getting back at it. I am looking to purchase a TS75. I recall that at one point they switched to a 75" rail. The saw I am looking to purchase is used and has a 55" rail so obviously it was prior to the 75" rail offering. The question I have is if the SAW has gone through any changes since then?? Were there any updates to the saw or are they the same now as they were back then? Thanks
