John, like you, I have been watching the price of Grizzly tools fluctuate. The other manufacturer still have "to the moon" pricing. For example, the Minimax s440p is currently "discounted" to $6,185.01. (The $0.01 was a nice touch.)
I currently have a G0513x2bf. The saw has many great features. It's stiff enough to tension a 3/4" Resaw King to 25k psi. The fence and the table tilt mechanisms are good. The motor brake is really nice. However, I've never fallen in love with my machine. Oddities I have noticed:
I have had trouble with the bearing guide alignment. I finally figured out that the surface of the bearings were not parallel to the blade. I resolved that by rotating the entire guide mechanism on the post, but that means one of my guides has very little clearance, even when fully open.
Second problem is the bearing guides get packed with sawdust. The lower dust collector port is below the guides and the bearings are not sealed, so they get filled with sawdust and fail. I was not in the habit of checking the bearings and a blade rubbed against the bearing, which didn't spin. That heated the blade, which caused the tire to fail, which caused the blade the break. (Or maybe the blade broke first.)
The blade detensioning mechanism works by putting the spring in compression. Most detensioning mechanisms I have seen shift the entire upper wheel assembly down. But the Grizzly saw doesn't do that. There is a bolt that pushes down on the spring from a fixed point as you detension the saw. By "detensioning" the saw, the spring is actually under more load. Also, since the detension mechanism is from a fixed point, the bolt used for detensioning has to be adjusted for different blade lengths or the detension mechanism doesn't work. What's worse is that if the bolt is misadjusted, you can't properly tension the blade in the first place.
Which brings me to blade lengths. Grizzly advertises that the standard blade length for the saw is 131.5". If you look at the specs more carefully, the blade length is 130" - 131.5". I have ordered 131.5" blades that were slightly too long, which meant I could not tension the blade properly. If Grizzly had made the standard length 130.75" or even 131", then the saw could tolerate blades that were a little too short or too long. Now that I know about this problem, I have considered just ordering shorter blades, but that means that I would either need to replace all my blades or constantly adjust the detensioning bolt referenced in the previous paragraph. I suspect a significant number of Grizzly users have had this problem. It's not easy to detect.
The base of the saw is quite flexible, which has led the vibration. I was able to mitigate that with Great Lakes castors, but the Grizzly manual says the preferred installation is to bolt the saw to the floor. If the saw were bolted to the floor, then the flex in the base would not matter, but I bet less than 1% of users bolt their saw to the floor, so that's really not a realistic expectation.
They used a cheap belt, which easily gained a set, which caused vibration. I replaced it with a Gates AX39, which has notches and that helped a lot.
So my saw at this point is functional, but all these problems I have had over the years have irritated me.
I would like to buy a saw that runs a 1" carbide blade, so I have considered the G0636X, but my experience with the lighter saw has given me pause. It looks like the heavier saw has the same detension mechanism, same bearing guides, and the same blade length issue as my saw. Plus the manual says the brake should only be used for emergencies, which I find very odd. I want to brake to stop the blade to avoid an emergency! Of course I'm just looking at the saw on paper, so I wondered if you had any thoughts about these issues with your saw. I know you have produced very impressive results with your saw.
