I went to a Rigid TS3650. The biggest advantage I found was the additional power when cutting some of my larger stock. There were occassions when even slowing down the feed rate, the saw struggled. Also I wanted to be able to use some of the jigs that I kept saw being demonstrated, that I was unable to do so do to the lack/layout of the miter slots. I also wanted one with a little more heft to it as well. Finally, I do try to practice safety on the table saw. The blade guard tended to be removed for extended periods of time - NOT recommended safety procedures! The TS3650 guard comes on and off by use of a thumb screw.
Now - all of that being said, I probably fell for the siren's song! 8-O If I was a bit more handy I probably could have adapted the jigs, and even built one of the very nice saw stands I have seen on BT central and some of the woodworking magazines. I also think had I invested in a nice, high quality blade I might have had a different experience with the binding as well. While I may have been able to use the BT3000 for some of the heavier cutting I have done recently, the TS3650 handled it easily.
I would recommend anyone thinking of changing saws to evaluate just WHY they are considering doing so. Look at what you REALLY cut. Of course, I have found buying new tools as part of the fun of the hobby. :eusa_danc
