I wouldn't even consider a granite top when I was looking at new table saws a couple of years ago. There's something to be said for the proven reliability of cast iron tops.
As to a particular brand, I looked at SawStop for all the reasons it's made. When I considered the overall cost, the expense and inconvenience of replacing the brake and a blade, and my threshold of financial pain, I opted out. I've been very pleased with my Grizzly G0690! Saved a ton of money, too!!!
