Ok...I guess i'll wade into this after my D70 experience... Since I returned my five d70's to Nikon I have done tons more research with respect to "dust" issues on DSLR's. It appears that despite what some folks say, ALL DSLR's will eventually be affected by dust getting on the ccd sensor...doesn't matter whether it's Nikon, Canon, Pentax etc... As an example, just check the forums at Dpreview for your favorite camera...search for "dust" Many say it's not a big deal...well if I spend $1500+ for image quality, I think it is... Bad news; 1) Most come with dust brand new in the box 2) Dust will be attracted to the sensor even if you don't change lenses (zoom lenses tend to suck air into the chamber) Good news; 1) Most dust specks only show up at high apertures with uniform light backgounds 2) Yes, the sensors can be cleaned...(do so at your own peril) 3) You can clone out the spots with your image editing program In response to Lostpatrol's comment that Canons tend to collect less dust than Nikons...it's possible, but many owners seem to feel that it's more a function of the distance between the filter and the sensor...Canon's is apparently further away, hence the dust doesn't show up quite as much. I'm not knocking DSLR's...or any particular brand...just be aware that if you are not prepared to live with dust issues then maybe they aren't for you. Personally, I am still disappointed and undecided.... PS...if you are stuck on Nikon because of your lenses...apparently they will have an 8mp (20D competitor) out this spring....it may be worth the wait.... PS# 2 Also note that not all of your older lenses will give you full digital capability/features. my 2 cents....

In youth, we learn....with age, we understand.
