I wouldn't expect this to be discontinued any time soon. Grizzly is selling the comparable model also, both of which I believe just became available this year. When I ordered mind from Matt, I asked him about other peoples feedback and he stated that he had 15 or so out in the field and hadn't had any issues. I don't have any idea how many Grizzly has sold, but I think at the price point, it can't be beat. I was leaning hard towards a PM-25 but the extra 200# of cast iron is what sold me. These two machines have basically the same table, with the 727 having a beefier saddle which is the reason for the shorter X travel. (but like I said, I am going to mod that a bit).
There are only two things that I didn't like / expect with my machine. The first was how much I had to shim the column on mine. I ended up at approx 1/8" of shim thickness on one side. The other is that when I moved the table all the way to the left, there was a good bit of binding in the handwheel. What I discovered is that when they drilled the holes in the table for the handwheel bracket assembly, they were off center a bit and this caused binding of the leadscrew when fully to the left. I removed the hand wheel bracket, tapped out the pins used to hold the bracket in place, and then reattached the bracket with the cap head screws so that it was as square and aligned as possible. Then I took a slightly large drill bit and drilled through the pin holes in the bracket and table and tapped those holes for 3/8-16. Then I just put in (2) new stainless cap screws to plug the holes. I don't think the screws would be needed to counteract the forces of the handwheel during milling, I just wanted the holes plugged.
I am still very happy with my purchase and would buy it again.
