...The Missus and I have purchased a Canon D20. Even after adding a 2GB Compact Flash, carry-bag, sales tax and so forth, we came in under the price of the new D30 before tax.
For me, the deciding factor was comfort. I had to bend my finger rather radically to reach the shutter button on the Digital Rebel XTi. The D20, being a little wider, felt very natural in my hands.
We hope to have some photos to add in the coming days.
