what smalljaw said - get a toaster oven that is designed for pizzas, etc - it will get to and maintain the temp - you may have to test it to calibrate slightly. (I've never calibrated mine - I set it @350 - put the timer on 30 - set the jig rack in it - come back in an hour - we're done.
There is a 'world' of difference between a $30 and a $60 model - and if this part of the process is important to you, spend the extra - it will last longer.
As for fumes - no, there isn't much - but 'sometimes' if you get a bit to much powder on them - there will be drips.
