the only ones you will find new with a mc jack will be in the Canon FS and ZR lines.
And finding one with both LCD screen and viewfinder will limit your selection.
None in the budget range will be "good in low light". For that you need larger lenses and imaging chips. Those camcorder start at about 2x more than you have budgeted.
