Well, in your position I'd decide whether I wanted to have things matching. If you are then buy a "nucleus" set you like the look and quality of. You non-stick - heavy base - stainless steel - etc.
If you are not worried and can make do with what you have got for a while I'd wait and see what comes along. I've collected a very good range of pots from here and there (sales, charity shops) by waiting and buying what's good and a price I can afford when I encounter it. None of it matches but that's of no consquence to me; it's all good in use.
I have heavy (Le C) stuff that I've had for years - some since early marriage forty years ago - but more recently have bought some excellent stainless steel (eg Fisslers for £3 a pan - in a charity shop! or a super ss Stella cbutterole in a kitchen shop which was reduced because it had lost its lid - other lids fit) or non-stick cast ali (techniques of ns are much better than when they began). They are there if you have time to wait and keep looking.
You'll probably laugh at a recent aquisition which was a Prestige ss frying pan with a really good thick copper base which I took the handle off and use as a roasting pan and is excellent for making gravy on a range; pukka roasting pans with that base cost an arm and a leg; this cost £1.75 in a charity shop and is perfect.
Well, that's my solution. Good stuff, very little matching but all excellent cooking stuff. And, yes, I do pay full price sometimes if I think the product is worth it to me!
Cheers Jane
