Help ! Need gas cooker recommendations please

MrsStepford

The Moffat which husband bought off our vendor is now on last legs. When we have new kitchen put in we'll go expensive. John Lewis has stopped selling own brand freestanding gas cookers so I'm stumped.

50cm wide max
side opening oven door
drop down lid
catalytic cleaning preferred
shelves which won't buckle under weight of a Le Creuset casserole dish
grill optional but inside top oven if so
knobs with sensible design so they don't get burnt
preferably not over £700, really want it under £500
nothing from Beko
easy to use for husband
no silly gimmick burner configurations

Any suggestions please ?

Thanks all ! xxx
