Vitaliy,

Your right about the odor. I have done a few boards using a toaster  
oven and found the best way to not stink up my basement, or destroy a  
board for that matter, is to always use double sided PCB.
If you are making a quick prototype and are only using one sided PCB,  
then the exposed backside will burn pretty badly. Also, putting a  
piece of fire-brick right above the board is also good in terms of  
getting more uniform melting.
My former supervisor did this in a small commercial oven to get a  
better reflow and it worked.
