I hate this thread cause it gives me F2 itch!
At the moment, my two main cameras are a Nikon F Photomic FTn (late "apollo" version - seen in my avatar) and a Nikon F2AS. I also have a Nikomat FTn that I use from time to time, and a Nikon F4s that needs a couple pieces to be useable (MS-21 insert for MB-21 and the DP-20). Both the F and F2 currently have motor drives on them. The F wears an F-36 with cordless pack that's missing the little contact plug, and the F2AS has an early MD-2/MB-1 drive on it. To make the drive lighter, I have lithium AA's installed.
Re: the nylon gear issue, it only affects later MD-2's, usually the ones with the black plastic anti-twist tabs. You'll probably be safe with a motor drive in the 400xxx-429xxx serial range. Mine is in the 423xxx serial range and works fine.
Why not replace it? They're very cheap these days, at least, when you compare their prices to what they were 3-4 years ago. KEH has BGN grade black F2AS bodies for $254.00, plus shipping. The MD-2/MB-1 drives have also come down in price. Not uncommon to be able to get one for about $100.
If you've the funds necessary, head on over to the KEH site and pick one up. Who knows, it might even wind up being your old camera.
I use it a lot... along with a Hasselblad 500CM
I have 2 and use them every other month or so.
I use an F2AS/MD2-MB1 as my "insurance policy" whenever I am shooting on back-country excursions, when batteries have a curious tendency to fail. As well, I rotate in and out throughout the year an F2A and a pair of F2s (DE1s, all with drives) in order to keep all in working order. No techno-phobe, I also use an F6 and a trio of F5s...
As evidenced by my .sig, I now have a pair of F2's. Black AS with MD-2/MB-1 and a chrome A.
