While I don't have the PM-25mv, I have a Grizzly with a slightly smaller table and my 6" rotary table fits well. Anything smaller and I wouldn't be able to do many of the parts I want to. My rotary table is also Grizzly but it needed some TLC before I was happy with it.
Yes, I have the H7527. The SB1364 looks like a nicer table but doesn't include the accessories.
On a side note, I recently had to cut a large arc on a part larger than the 6" table so there was no way to clamp the part on. I bolted an old disc brake rotor to the table first and clamped the workpiece to the disc. It worked well as a light duty table extender.
