used one for years, until we installed an unvented propane heater on the wall and didn't need the kerosene anymore. it was very handy one time when we had an ice storm and lost power for 10 days.
i loaned it to a guy to "try out", and the ****er moved away and never gave it back to me.
this was about 15 years ago...probably better now than they were then. can't remember the brand name of it.
