I love the Oktava MK012! It has a wee bit muddy top, but all in all it sounds good for it's price. Myself, I nowadays use mostly Sennheiser MKH-microphones, but my old Oktavas is still in use, though now for different forms of sound design-chores and for perspective sounds.
Handling-noises IS a problem on this one, you can't just grab it and hope for the best, but you can learn to work with it. Of course you'll need a good suspension, but once you get a hang of it, it's well worth it. The suspensions from Line Audio intended for their CM3 are fairy good ones, but Oktava's own suspensions blows on an epic scale I'm afraid.
As Andreas already noted though, the Line Audio CM3 is a very very good microphone for its price. The >only< reason mine isn't in much use anymore is because my MKH40's does the very same thing better....but in it's defense, when I got the 40's they where about 24.000 SEK a piece, whereas the CM3 was 1.000 SEK... One dollar being about 7 SEK/1 Euro - 10 SEK/1 Pound - 12 SEK. Still use it for vocoders though! And still the MKH40's was the only microphones that could replace it!
The characteristics the two microphones apart though are very different, so it's not as easy as one could have hoped to say which ones the better one. CM3 has a softer sound less sensitive to acoustics, but demand more work in post, whereas the 012 have a more intelligible sound for speech, and can change capsules, but leaves much less options in post. If I were you I'd go for both if possible - different locations demand different microphones. And once, I did :-)
