During this blog I will suggest some youtube videos to watch and give you a review as to what features they have which will help you plan your oven.
I found this great FREE software that allows you to download youtube videos, WHY download them? well you probably will watch them many times and it will save time and bandwidth for you + it saves you sifting through other ones to find them again incase you forget or don't mark them properly (like i did).
