Yeah, of all the research I've done, other than paint, the biggest difference seems to be in the different diffuser setups.
Thanks guys.
Grate elevations ?
3 point or 4 point suspension ?
1/4-20, 12-24 or 10 -24 suspension bolts ?
How wide of a lip to leave after the cut ?
Those are a few more to ponder.
Edit:
I believe Chad reported that the IMUSA pot required some re-shaping at the top lip to get the SJ lid to fit.
Most Vasconia 32 quart users report a perfect fit, top and bottom.
