My Fiancee and I are looking to buy a digital SLR. Both of us have a bit of experience with SLRs (Her D, and me not so D).
She's an artist, and enjoys artistic photography, where as I like to take pictures of nifty things. For me, the main draw of a DSLR is the autofocus time. I want to be able to take pictures of things like wildlife on the side of the road, as I go past.

We've been looking at the Canon range, partially because that's what her dad has, so lens interoperability is nice, but partially because the Canons have 8MP, whereas the Nikons have 6MP.

If we're going with the Canon range, I want something with the Digic II processor, so that eliminates the 20D. I don't think we're ready for something over $2,000, so we're not going to be looking at a 5D.

That leaves us the 350D (Digital Rebel XT), and the 30D. I can see what the majority of the technical differences are between the two, but I can't tell how any of those will practically affect us.

So please leave suggestions of which one fits us best--or tell me about one I've completely neglected--or let me know what the practical differences between the two will be.

Thanks!
