This one burns really clean, actually. I know what you're talking about, and I really only get a whiff when it runs out of fuel and kinda puffs out at the end.
It's well below freezing here currently, and I needed to do some repairs to my truck so I had to warm up the garage. My kero was empty, but I had 5g of diesel. I was a little gunshy about feeding it diesel, but...no odor, no smoke. Nice and clean. I forget what brand, but it's red...red torpedo, black belly tank for fuel. I've been extremely happy with it.
