I know you said other than Z-man, but man do they have some good options. The TRD Bugs and TRD Hogs are great beaver / creature profiles, while the TRD Craws are amazing realistic craw baits. On the latter, the way the claws float up off the bottom just looks incredible...I caught a bunch with those on a 1/8-3/16 finesse jig this year, and what amount I did fish the Ned rig caught quite a few on those as well. The durability doesn't hurt either. That said, there is the issue of storage that some don't like, and the issue of getting them to play nice with certain bait keepers. I still don't think you can do a lot better than the TRD Craws for a Ned craw bait though!
If it's a matter of not liking Elaztech, there are quite a few mold makers that have basically knocked it off at this point. If you find someone that has one they could make them with normal plastic.
What I really feel like is missing from Z-Man's lineup is something similar to a Rage Bug or Z-craw, a sort of beaver profile with action "claws." As mentioned above, the new Strike King Rage Ned Bug looks like it will work really well there, though this is getting away from what the OP seems to be after. I'd really, really like to see both Ned size and "regular" size offerings from Z-Man in that category.
