D200 and D70 - best bang for buck 50mm?

Could you please be so kind to recommend a 50mm prime for a Nikon D200 and D70? I'm a micro four thirds user, so I'm a bit out of my depth here and a friend has asked for a recommendation.

I'm looking at the Nikon AF Nikkor 50mm f/1.4D - first, would that be natively compatible with the D200 and D70, and second, are there better value for money alternatives?

Much appreciated (yes I'm doing my own research, but there is a lot to wade through).
