I have the Pampered Chef sets that I got before the price became outrageous. And Princess House stainless steel ones because I was a consultant.
But- I have some cheap kind from many years ago that I pull out all the time because they are "tried and true". So really, cost doesn't matter.
I hate 3 sets of pots and pans because I cooked a lot when the kids were home. I've bought the Paula Deen ones for wedding shower gifts lately.
