By the way, who cares if people who can afford nice cameras but don't need them buy them anyways? Frankly, the more people who buy that 40D, the cheaper Canon can make it -- supply here isn't really limited for most of these cameras, so increased demand will only drive up economies of scale, encourage continued innovation, and allow for cheaper, better cameras.
Someone doesn't remember high school economics
I really don't care if someone goes out and spends 2000 or more dollars on all their stuff. What I DO care about is who has been feeding this misinformation BS to them and told them they couldn't get by with anything cheaper.
I've noticed that some of you guys posting aren't what I'd call newbies. By newbie, I mean someone who has never taken their Point and Shoot off of full automatic mode. I've been noticing some people on this forum and others that have no idea what they're doing and still have some 1000 dollar camera and another 1200+ bucks in lenses.
If you can utilize it, by all means utilize it. If you want a higher end camera, by all means get it. I completely understand the whole "grow in" mentality. If you buy higher than pricepoint, you will spend less money in the long run and you will learn quicker. I believe that only works to a point though. Give a newbie a 1D Mk.3 and watch him get intimidated.
All in all, I spent roughly 800 dollars on everything I have- camera, lenses, bag, tripod, flash memory, filters, cleaning supplies, etc. I've been a hobbyist photographer for about 2 years. I used to play with my dad's SLR when I was really little and he would develop the pictures for me.
Even if I had the cash to get a 20D, 30D, or 40D, I would have still gotten my 10D. We'll see in the next few weeks what I can do with it, when I have the time to go out and take photos again.
I got a D40x with a big fancy lens cuz it makes me look like im good. It just makes me feel better about myself thinking people think im taking better photos then them cuz I look bad azz with my gear!
Looking through your gallery, your photos are pretty good. A testament to what you can do with a "lower end" DSLR.
EDIT- also clarified the OP.
