Pentair 4000 SMBW-4060 Grid Replacements

[Ishinc]

I have an older 4000 Pentair 4000 SMBW-4060 DE filter that is in need of a grid replacement. I've searched but can't find a good replacement set. I believe the filter part number is #074925 for the Pentair part. Anybody know if there are other replacement brands and model numbers I can use? What options do I have?

What do you consider a "good" set? There are several aftermarket grids available, but that is an older style DE filter (originally made by Purex) that isn't seen a lot anymore so there aren't as many options.
Unicel FG-1260 is a good substitute, but can be nearly as expensive as OEM.
