Shirogorov will be really hard to find in retail, and the price is not going to be pretty.
Look for Kizlyar (but not Kizlyar Supreme - that are Chinese-made knives: you probably would not want to go to Russia to bring back a Chinese-made product), Cheburkov, Sander.
Kizlyar knives are reasonably priced production knives, Cheburkov is more semi-custom, but still affordable. Sander knives are quite good, sort of hand-made and again well priced.
Essentially you can buy whatever Russian-made knife you like, it will likely be of a reasonable quality. Look for either 95x18 steel (stainless) or x12мф (an equivalent of D2): that can be used as an indication of the quality of a knife itself (besides the price, which sometimes can be misleading).
That's for fixed knives, there will be lots of them and they will be more affordable. There are not that many Russian quality folders, and they will be pricey: essentially Shirogorov and Cheburkov is all that I would consider buying myself.
P.S. And I do not think Shirogorov will be much cheaper in retail there, or cheaper at all! That is if you find it! Do not spend too much time looking for a deal on it, it will be pretty much a waste! Moscow is an expensive place: you will see that.
