Looks like a very useful item. I may cave - I'm getting talked out of the grill pan idea, per the ever-growing thread I started.

I bought a wok once with one of those rings - no way would it get hot enough on an electric coil stove. I DID keep the tools tho - it came with a nice skimmer and some other doodads.

I even bought a wok cookbook - but it stated that the recipes could be done in any lowsided skillet.
