To make sure you get a legit Octava, you can go to Sound-room.com - they even have a DVXUser discount - enter the coupon code DV on check out for like a 5-10% discount. I've bought from them, as have many of the folks that hang out on the audio forum here.
I like it too much to sell it right now. Buy from the Sound Room, the guy is legit and it is the best place to go that I know of to get a best bang for the buck Mk012. Be very carefull of other places as there are a lot of fake ones running around.
