Yeah, I do. Do I just look at how much it's priced in Russia and then divide that by the current market price of keys?Do you already have Enhanced Steam installed? If not, I'd (obviously) say start there. That will give you the game's price in other regions, including Russia. It'll also give you a handy SteamDB link on the store page so you can check for any crazy sort of region-locking.
I just checked and there's one pesrson with it, and they're looking for a key, refined metal and real money. I don't know if they just want 1 key AND 1 metal, or 1 key OR 1 metal.Good place to check is TF2 Outpost, just make sure you change the search option to "Steam Inventory" before you enter the game you want, otherwise it will only look for TF2 items with that name.
