There is a reason why the 416 is THE microphone out in the field. Please note 'out' as it should be used mostly in exteriors (or larger interiors). It not only sounds excellent, it'll last a lifetime and will always work. Buy a used one or, hell, buy a 415T (you'll need a cheap 48V to 12V ab tingamajic) and save a few hundreds!
Schoeps, as we all know is excellent and probably a bit over qualified. But if you do, the mk41 is the right capsule and definitely not the MK5.
The Rode NTG-3 (I haven't used it so far) is a copy of the 416 and, if copied well, should be as good as......
The Sennheiser ME (66) line is a budget line and sounds like it. Buy if you can't afford something better.
Oktavas are cheap but not recommended for field use - there's definitely handling noise issues. BTW, as good as Schoepses are, I don't leave house without a backup as they tend to react to humidity every now and then.....!
Excellent mics and to be found for incredible low prices on fleabay is the AKG series 460/480 together with a CK63! OK is the AT 4053. There's also some copy of the 'schoeps' from Shure, I forgot it's name though.
And, because that was mentioned too in this thread, it's not at all difficult to windshield a Sennheiser 416 - why would it? You can go for a full 'rycote-style' windshield. Funny to call it that as 'rycote' actually copied this design themselves - or you go, and that's recommended for your uses, and get some kind of 'flurry' that's just slipped onto the microphone. It's easy put on and off, doesn't cost no arm or leg, and generally does the job.
Final advice: go get a used Sennheiser 415T (to be found as low as 300 bucks!) and with the rest and a little bit added get a sound devices 302 audio mixer and a nice pair of headphones and you're there!
