The first was a two-slice Kenmore (RIP Sears) which still works. It cost $20 and was purchased close to 25 years ago. I only used this a couple times a week and now the usage is very sporadic, but it always works when I need it to.
The second was a Cuisinart toaster oven, which is not exactly a toaster but has ended up being our primary toaster. I have no idea how old it is since we bought it at a garage sale for $5 about 5 years ago. This is used almost daily, sometimes multiple times a day, and for a lot more than just toast.
I can see buying one more toaster, meaning a toaster oven, in my life, but it will probably be to get new functionality (e.g., air fryer, larger capacity, etc) instead of replacing something broken.
