A question I have a lot of experience with-
I have used a toaster oven almost exclusively when baking, from before I was married. (That's over 10 years ago, at this point). The real oven gets used about 4 times a year- the three major holidays and maybe one more random time in the year. Now keep in mind, I have 4 children and it cooks everything we need to feed them and us.
I've used Kitchenaid, Hamilton Beach, Black and Decker, etc...
The Hamilton Beach one that Gewehr98 linked is the one we are currently using. Previously, we had a Kitchenaid with dials and before that, one with a digital readout.
My first piece of advice: the under $100 units are to be understood as disposable appliances. I don't know if the over $200 are better built, but the under $100 units last, at best, 3-5 years.
For example, after 1 year, the convection fan in the Hamilton Beach has started whining and grinding.
The older Kitchenaid had its digital readout
start malfunctioning after 3-4 years. It still worked for 2+ more years, but was annoying. It was actually the best performing of the ones we have bought because its heating elements and fans all functioned excellently. We decided to look at ones with dials to avoid the digital readout's failure and found that it failed earlier and with more concerning results. (When switching from Bake to Broil or Toast, it suddenly got very hard to turn and then had a large "Pop" followed by smoke, after about 2-3 years of use.) We replaced that one with the Hamilton Beach.
If you accept that they are not particularly long-lived, they are wonderful appliances. Snacks, breads, casseroles, pork loin, meatloaf, chicken, pies, cookies, etc...- so long as it fits, you can cook it well. I like to make sure I buy ones that will fit my cast iron skillet and chicken fryer. The toaster oven heats up much faster than the real oven, and it less hassle to just pop something it for reheating that you'd like to be crunchy, not soft. Leftover pizza from the microwave is nasty. Leftover pizza in the toaster oven is great, for example.
Each toaster oven will be different- some will heat the rear more quickly than the front so you will need to turn your food halfway through cooking. Some heat better than others.
I will say, while the Hamilton Beach has been acceptable, aside from the fan issue, (the ability to cook things on separate racks is very nice), the digital Kitchenaid was the one I was most satisfied with.
As I am looking for the model (which I can't find since it was probably 5-8 years ago that we bought it. In fact, it may even have been a wedding present), it seems that the digital Kitchenaid Models start in the $150 range. That might explain why it was the longest-lived oven we had.
So, for longevity, you may want to bump up your price a little. This is probably the closest to what we had:

This may be the current version of ours, but it looks quite different as well:

likely means longer lasting.
