DSLR Rant:
1. The quality is good, yes, but most dslrs have one CMOS chip as apposed to the 3 CMOS or 3CCD's of most good video cameras. Thus, DSLR's will have less dynamic colors and are not able to pick up colors as accurately. The censors are smaller, so the lowlight performance is much worse.
2. Lens options are very limited. Yes, DSLRs have lots of lenses, but for filming scootering/skating, you need a fisheye, and DSLRs have very few fisheye options.
3. The audio is terrible. the stock mics on DSLRs are absolutely terrible. The audio sounds harsh and scratchy and you need magic lantern or something like it to get even acceptable quality audio.
4. Battery life. The battery life on DSLRs is horrible. Even with an extended battery the camera overheats and has to be shut off. I know t2i's are especially prone to overheating while filming for a long time.
5. Overall the comfort of filming with a DSLR is not good. They are not well balanced and they are very uncomfortable to hold and shaky when filming lines.
6. DSLRs lack a lot of setting that camcorders have, such as steady shot and ND Filters.
So overall when you get a DSLR the initial cost is only about half of what you will need to spend to get a decent setup. They are money pits.
