Britannia make a lot of range cookers. They vary from the 90cm E-Line for about £1,899 to the huge 150cm Sigma or Classic ranges for around £9,499. All of them are available in stainless steel, some are also available in black or graphite, others also have a cream version. They're well made and very popular with keen cooks.
There's also a Colourange service available on certain models whereby you can choose your own bespoke colour. That adds quite a bit to the cost, though. About £1,500 for a 100cm twin oven Sigma model.
