I have a built in microwave over my oven and I pretty much only use that to heat something up quickly. I do NOT use it to cook at all because I prefer the oven or toaster oven for cooking.
I have a Breville toaster oven (about $250 at Bed Bath and Beyond) I bought to replace my Kitchen Aid toaster oven that was a little smaller ($150) but still a very good toaster oven.
Back in 2015 my oven went out and it was our plan to replace it by Thanksgiving. My husband died unexpectedly in October of 2015 and I have used my toaster oven for everything. At Thanksgiving, I brought out the Kitchen Aid toaster oven an used it as well. I made cornish hens in the toaster oven and all the other traditional dishes and it was great for 2 years now!
In March, I replaced and updated my oven and microwave and I STILL gravitate to the toaster oven. When I use my oven, it still smells new and it is SO pretty I don't want to mess it up!!
I understand you have teens. When my daughter was living at home, she used the toaster oven more than the microwave as well.
It is just me now so the toaster oven is very practical for me and it is my go to for cooking.
