I have read so many different threads on this forum about camera noise from the Canons, and even on the modern DV ones so a good idea to steer clear of them IMHO.
I have always owned Sony camcorders and on this forum they also tend to be the most popular choice. You do pay a bit of a premium on the price for their cams, but they are well worth it IMO.
I don't know about the new models as I am not in the market for a new cam at the moment but a very popular choice on here is the TRV-33 or the slightly cheaper 22 & 19. I'm not sure if any of these have been replaced with newer models so will let others advise on that.
If doing a lot of filming indoors etc with lw light then yes you can add a video light to a camcorder. These range in price and obviously quality and you could pay from around £30 up to several hundred. Some will take their power from the camcorder and some will have their own battery.
Take a look
Here for a fair range of video lights.
Mark.
