I got the Sunpentown a few years ago. I don't use it too often, it's my 5th burner when I'm having a big dinner or canning, etc. I also use it when the grandchildren are helping me cook something, since I don't like them hanging over the gas cooktop.

It works.

It was about $100, on sale, at Amazon, when I got it. I had to buy a couple of saucepans, but I have cast iron pans that I use most of the time.

We've got a Waring Pro that works just fine. I don't remember the exact price, but probably less than $150 on Amazon. We only use it as a supplement now, but had to use it as our only burner for about 4 months while the kitchen was being finished. I have All Clad, also, and picked up a couple of pieces of very inexpensive Ikea cookware to supplement.

One vote for the Max Burton. It's around $100 and mine works great.
