Trying to decide on a DSLR. The deciding factor is low-light performance... but I'm not sure how good is "good enough." Principally, I'm waffling between the Canon 5D and the Canon 5D Mark-II, which seem to vary almost exclusively in their low-light performance. However, since the "Mark I" 5D has a full-frame sensor (and therefore should have much better low-light performance than any smaller sensor out there, based merely on quantum light noise)... is it good enough for flashless inside photography? The price difference is basically 100%, since I can bet a "Mark I" for $1k used. Personal experiences, please?

I've had a Canon 5D Mark II for about 2.5 years, and I've recently noticed some bad dust particle issues that are on the sensor or mirror, not the lens. Can someone recommend a good camera store in New York City that could do a good professional job of cleaning my sensor (and an idea of how much this will cost)? I've looked into cleaning kits, and I think I would rather have a professional do it. Thanks! [more inside]
