Go have a look at what they've got at TKmax, assuming there's one near you. That's where all my kitchen stuff comes from, mostly end of line or incomplete sets.
I'm also short of cupboard space and a hard anodised saute pan with a lid doubles up as saucepan and frying pan, also goes under the grill, occasionally in the oven. Cost £40 when it was still being advertised online for £70. In addition I have that a three tier SS steamer (base can be used as a big saucepan or casserole) and a medium saucepan. That's it, I don't need anything more for the hob.
