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.

I have a 4" for my PM727m, too small to do much with. By the time you get a part on it there is very little clamping room if any. I would go no smaller then a 6

thanks , is the grizzly model # H7527 ?
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.

I bought a 6" RT for my PM25 when I had it. The 6" fits well within the work envelope of that machine. I no longer have the PM25, but I still have the RT and use it on my bigger machine.

Perhaps this question should have it's own thread. What is the advantage of an indexing head over a rotary table with indexing plates?

Might try the grizzly 5" comes with index plates and tail stock, I am happy with mine after I worked on the chuck for a hour or so to smooth it out.
