Thanks all for the replies. I forgot about those Coleman grills, but I always thought they were isobutane or something. I already have 2 camping stoves (an MSR and a Whisperlite), so maybe I'm biased towards that fuel.

I'll look into the Coleman 2 burner. Have lots of fond memories with them and my parents growing up ... would love to pass them to my kids.

Now to price the adaptors out.

is this what I'd need to run a regular propane tank for a Coleman grill?

For this grill (or should I go with the standard, 10K BTU/burner grill?)
