Welcome to Nikonians. While being a very good camera the D70 is far behind what the D7000 offers. I had the D70s and really liked it but wanted more resolution, better ISO, better remote possibilities, etc. The D7000 does require you to use better technique because of the increased resolution but once you understand that you'll really enjoy the extra benefits available.
Nobody should seek his own good, but the good of others. <><
