Well considering all of that, forget the n6006 and use a Nikon F or F2. Or a Nikkormat, I have the Nikkormat and it is absolutely fantastic, all the heavy metal kerchung of the F without the pricetag. You can find them for next to nothing, I have seen flawless copies trade for as little as 25 dollars. I got mine free in a lens deal, I purchased a set of lenses from a seller on Craigslist and he threw it in for free.
I also purchased a Nikkormat FT2 for 40 bucks with a 50mm f1.4 pre-AI, which is a regular Nikkormat with a flash hotshoe and the ability to meter AI and AI-S lenses. I ended up selling it for 100 bucks with a 28 f3.5 attached to it.
The only caveat is you must use a shutter cord with a locking mechanism, I made the mistake of buying one that doesn't, unless you want to hold a cord for 5 hours.
Do not use the Nikkormat EL, it has an electronic shutter and thus uses batteries. All other Nikkormats (I have the first-generation FTN) use a battery for the metering system.
Also, this may or may not be myself bragging about the low-light AF of my EOS Canon 5D digital, but I can AF it at night using radio towers in the distance with their indicators on. I set the focus to center focus, set the metering to spot metering on AF point (not necessary but I find it helps) trip the AF and I'm golden. I have used it to AF a lens that went onto a 35mm EOS with poor low-light AF with success. I'll AF it on my 5D, mark it with something in case it moves, set the focus to manual and turn off the stabilizer, throw it on my EOS 650 and get tack sharp exposures.
