Greetings!
I generally buy my kerosene stuff used. Sometimes thrift stores, flea markets, yard sales, or Craigslist.
For the last couple of years I’ve been wintering in Minneapolis & Duluth MN. so I picked up a big 23k BTU kerosene heater for the harsh winters. It’s a Sears brand, but I don’t know the model #. I paid $10 for it, and $5 each for my 2 kerosene heater/cookers at a yard sale. They are Bunsen Sports Heater/ Stoves. They’ll go from simmer (unknown BTU’s) to maybe 12k BTU’s on high. Many people use this stuff for camping.
I don’t know that brand makes much difference, but BTU’s and the ability to use them for both heating & cooking does make a difference. For most people the two heaters/cookers would fulfill all their needs.
Cheers!
