I have a Kitchen-Aid single slot toaster that does a great job. Unfortunately, like most everything that works well, they discontinued it. I even had to buy a refurb because new ones were no longer available. That one's in storage.
Last year I bought another single slot one from Amazon. I forget the brand, but it has a see-through window in the front so you can watch your toast get brown. Instead of nichrome wires it has four rods that heat up. It would work great except the top front rod isn't adjusted right and it runs way too hot. I have to put the toast in upside down, leave it for a minute or so, then turn it over and let it go another couple minutes. That produces reasonably even toast. Without flipping the toast you get nice browning except for the upper portion of one side that's completely black.
As long as people have been making toast you'd think somebody would have developed a toaster that works well and doesn't fall apart in a year. Sadly, such seems not to be the case.
