ok so i bought this toaster oven at a garage sale for 5.00 and got it home and pluged it in a turned it on and stuck a tempature probe in the top of the oven and then set oven for 350 deg. and let it heat up and well never used a toaster oven before and so not sure what is normal but this thing when set to 350 deg. will swing 50 -/+ from 350 deg is this normal and will it work for curring powder paint on jig heads and stuff
