Low Light + fast continous mode

[d-sr]

I'm looking for a good low light camera with a fast continous shot mode.
My Panasonic camera will take and record about 35 frames - 4MP every 20 sec. but it's not verygood in low light. I really don't want to replace it, but would like to get another camera to go with it for the low light stuff. Fuji has several with ISO of 800 & 1600 that take great photos, but they are unacceptably slow in continous mode, about 5 frames in the same 20 sec.
Does anyone have suggestions?

Thanks, Don
