The thing about the Advantium (and other less-featured convection microwaves) is that it can be used as a second oven. For smaller items, it can be used as the primary oven.

In 2009, I put in an Advantium (the stronger of the two choices at that time) and a GE Profile Induction. No flex options at that time. We enjoyed both and used the Advantium mostly as a microwave and second oven/warmer/proofer. I tried the nifty speed thing a few times and it worked as advertised. It put on quite a light show, but old habits die hard and then we moved. We have had gas in the last two houses. I loved induction for many reasons - ease of cleaning, power, responsiveness. But, we like gas more - just something primal for us. Also, we cook a lot with cast iron and I missed banging things around with abandon when we had induction.

To be clear, cast iron is perfect for induction. What Nightowl missed was the banging things around.

From the get-go, I intended to use my Advantium 240V mostly as a microwave and secondary oven, and to use the speed cook when I needed to make meals fast. During the extended remodel, my pressing need for quick cooking dried up, so I haven't taken full advantage of the speed cooking. There is a big learning curve with it. Sometimes it can be a lifesaver--for the meal at least. I've rescued a number of items with Speed. I might choose to use it for many more things if I had the need, but when I have time to dawdle and three other ways of accomplishing it, I don't bother.

I can say that the Advantium has the best microwave I've ever used, but I'm not a big microwaver. Several things get zapped daily, but mostly only for a minute or two. It's a very expensive way to watch a machine deteriorate. Every time you use a microwave, the mechanism degrades.

If you intend to maintain your current cooking habits, I don't see what advantage it would give you.

I have the Advantium 240. I use the speed oven quite a bit for re-hearing including leftover pizza and even tried leftover pancakes once.(To my surprise, they were excellent)) At holidays, I use it to cook a casserole

i warm my plates in it as well.

I didn't find it that complicated to use I either find something similar in the pre-programmed items or punt. You choose how much top hear, bottom hear, convection and MW you want to use and pop in the food. The settings are not critical so you can experiment. It comes down to how fast you want to cook something. I use a lower top setting with a frozen deep dish pizza as it will take longer to re-heat than my home made pizza with a thinner crust

i do break the rules and seldom cook directly on the trays but use my old Corning items or an oven safe porcelain plate

i did program a few things for my DH and other than putting the metal tray on top of the glass tray the first time, he does use it

With just 2 of us, I didn't need 2 ovens. This was a great option for us. I have been pleased with it 3.5 years). DH even uses it - both as MW and speed oven.

In your case, it might not be used as much and a Sharp MW might be cheaper.

If you do go with the Advantage, splurge for the 240 version and include tray storage

Oh and induction rocks!

My experience is similar to gemini above. I've had my 240 for 10 years now and have occasionally posted about it on this site. I use it daily as a speed oven. Last night I made stuffed peppers for 4 in it in 17 minutes, and they were roasted, browned and identical to results I would get from a conventional oven in far less time. Large casseroles are cooked quickly, and then you can top brown the bread crumb or melt the cheese with the upper halogens. If you use any processed foods, like breaded frozen fish, for instance, that gets done in about 6 or 7 minutes, browned and crispy. The programmed settings are pretty extensive, and the cookbook and cooking guide that come with the oven are excellent. The directions, times, etc. can be easily adapted to any dish you want to make. Good luck with your decision! Appliances are so expensive, I know you want to make the right choice.
