I was going to say somthing before but sounded hippy so I didn't bother.
That being said I don't like aluminum pans.
I like this kind Cooker
this type in stainless with a strong yoke across the top are the ones I like
Make sure it fits your stove....
If your going to can try and get one that will fit 4 mason jars at a time which will handle a couple of Lobsters as well
