for 10g+ I'd use

or just find the bare burners if you're looking to build your own stand.

I use the 20 tip models on my rig. I love them, even thought they get some bad press here. The 10 tip ones are the perfect size w/o being over-kill. You can also convert these to NG with a simple drill bit. You have to do some testing for distance from jet tip to kettle.
