I know they are expensive and looks like you are looking at used, but I'd go SawStop. Up front price is expensive, but not nearly as the bill the comes in from the various doctors that stitch your digits back on. I've seen what happens when an aluminum miter gauge trips the stop mechanism. Damaged blade was sent back to Forrest to be checked, they were able to fix and then resharpen the blade, the miter gauge has a nick, but very minor.
I know it's not the advice you are looking for, but you get it anyway.
Especially since I see you are looking at putting together a home shop.
