I'd recommend buying the pieces you use and getting professional level. Too many of those set's come with items that wind up wasting space. No sense having a steamer insert if you never use it.
I keep an 8 qt stock pot, 4 & 2 qt sauce pots, 12" round lodge cast iron pan, 9x13" rectangle lodge cast iron casserole pan, a 12" stone earth Ozeri, and 8" Vollrath non stick.
Those cost me much less than a high end 'set' and are much better cookware.
Yeah, I am not hell-bent on a full set. I don't have the space and what works in a pan may not be the same as for things you cook in a pot which is why I'm cool with buying individual pieces or small 2-3 pan sets. I don't care about uniformity.
