For stovetop toasters this style is hands down the best toaster though it will only do 2 slices at a time.

Not sure why this link isn't hyper.... we've used a very similar one for years now, and payed much less than what Defender is asking (this one is probably SS, but the regular ones last a couple of seasons at around $10)... check RV outlets and other camping stores.
Today's electric toasters all do seem to be quite large in footprint... try some second hand stores for old ones like your grandma used to have!
