FoxBot is the only one I know of for the Ukrainian grey digital camo schemes. They're a Ukrainian company, and I have their 1/32 decals and mask set for the Su-25. I hit a snag in my build due to Trumpeter's horrible fuselage alignment issues, so I had to set it aside for a little bit hoping for an idea to pop into my head for how to correct the alignment issues. The FoxBot stuff seems to be good quality from what I have seen.
Just in case you wanted to see the Trumpeter Su-25, I have a WIP thread for it here:

Keep in mind that I'm using lots of aftermarket stuff on it and have scratchbuilt a lot of stuff on it, so it is in no way a representation of what an OOB build would look like.
