There is a strong school of thought that if you shoot without a meter and really review your shots you can get the exposure right a whole lot more than you expect. Add in the histogram in the back and you have instant feed back. Just make sure you display the image with the histogram long enough to decide what you want to do (e.g. another exposure).
The main lenses I am going to use on my DSLR (right now looking like a D3000 or D60) will be the CV SLII 20 and 58, both chipped and a 180/2.8 ED which might get traded in for an 180/2.8 ED AF. I have several other lens I really want to try (e.g. 24, 28, 50, 85, 105) but I want full manual metering in the viewfinder for most of my efforts (getting lazy in old age). That might change if I get better at guessing exposures.
Give it a try, pick up an old 24/2.8. It's a great lens normally and makes a kick ass 36/2.8 on your D70. Small, sharp, reasonably fast and a Nikkor.
