210 parts for 25 bucks?! That's a great bargain!
The Russian paint they reference...is it AKAH? If it is, you can find the Akan paints state-side at Linden Hill Imports. Just be aware that you might not find Akan paints to be a good value. I ordered a set of 6 of them for my Su-25M1, and every single bottle (small bottles) was only about 1/3 full...pretty sure that's how they come from the factory, since they were in a sealed package and there was no evidence of leakage inside the bag.
MRP-195 is a good paint that matches the unique color of Sukhoi cockpits if you're looking for a place to start.
