Got mine from Ikea, they were an absolute bargain last year.
I would say any cheap set from a supermarket or somewhere like that. Nut try & go for stainless steel, as the cheap non stick ones tend to rust as the coating gets worn away.
Specific camping cookware is quite expensive when compared to cheap household stuff, which is fine if you're backpacking or lightweight camping, but if you're taking a car & have the room, you might as well save a few quid & have some pans you can actually cook with.
God luck anyway

I believe Tesco Value do a stainless set with 3 pans (not certain though) & of course there's the legendary Ikea blue frying pan (the best £2.50 I ever spent!)
4 Canvas tents (various sizes)
3 Plastic tents (various sizes)
& 1 Tin tent (yes, I'm a turn-coat, but it has a canvas awning)
My other passion;
My 1983 BMW 525e
