Comparing those two cameras is like comparing kiwis to lemons

The D70 is more in direct competition with the Canon 300D (Digital Rebel) feature and resolution wise.
I have had the 300D for about a year now and love it. Supposedly the D70 has better metering and a few other features that might make it more attractive than the 300D. Aesthetically the D70 is much nicer than the 300D, it looks a lot and feels more like a sturdy professional camera. But.... for the money the 300D is a steal..... right now you can snag a 300D with the 18-55 EFs lens for around $660 after the $100 rebate that Canon has going.
