I am a reliability engineer.... by nature I am extremely risk averse.... its in my genes, as my Dad was the same. He told me buying quality is like buying oats for the horse, you either pay top dollar for top quality oats, or you can by oats that have already been through a horse, which you can buy much cheaper.
But really, what I want to delve into is gimbling and possibly getting a two part set up, fixing the oven but gimbling the top.... as well as a general instalation chat with someone who has the experience.
