Ok, my second try:)
Skolkovo is surely a nice place to be. It could be the best Russian MBA, but not the best MBA available in Russia. Especially for 90k. Skolkovo is great if you're a business owner and need "connections" within Russia's power circle. Or when your goal is to work for top Russian state-own enterprises. So for 90k you could buy a pass. But I'm not sure of it's transferability for international market. And it's a bit of vanity fair.
If one really need to stay in Russia and get a prime world-recognized EMBA, my top choice would be HEC\St.Pete University double degree EMBA (
http://www.gsom.spbu.ru/en/2demba/key_facts). At 52k you can't bit it.
Then there is Robinson\Moscow University double degree (
http://robinson.gsu.edu/moscowleaders/index.html). At $65k
Finally, there are Stockholm School of Economics EMBA programs (

At below 30k price tag - where I'm actually shopping - the top choice is Vlerick's EMBA. It may be ranked above the SSE one, but SSE is a better brand in Russia and has better connections to the Russian business.
Then I would place Antwerp Management School EMBA - double degree with Russian partner (
http://www.engl.emba-uams.ru). But it presented mostly in Russian.
Also, there is a part-time Grenoble MBA program (
http://www.grenoble-em.com/default.aspx?rub=1063). Double degree with Russian partner, partially in Russian. It's surely good one and a real value (Euro18k), but it's not EMBA.
