Hi all, my microwave oven has packed up- it was a very basic model when I bought it and lasted me well over 6yrs. At the time it only cost me £40 (£39.99). However since then a lot has changed- mainly I have a young child, work and energy prices have since nearly doubled. There are a few questions I need to investigate and I know that others who use these forums will have considered them too. 1. Is it more fuel efficient to use a combination microwave oven to cook a roast chicken then a fan assisted oven? 2. Would it be more cost effective to buy a basic microwave oven (cheaper & Simpler engineering, less to go wrong) than a combination oven over (more expensive, complex engineering, a lot more to go wrong) 3. Has anyone created a graph, spreadsheet or formula for calculating the graph yet? Thanks, BPG (serious questions- number 3 may not have get any answers- just wondered if someone has actually done this).
