Hi there! Based on the search results, I would recommend either the Le Creuset Non-stick Rectangular Oven Tray Small for R549 or the Jamie Oliver Baking Sheet 35X27CM for R199. Both of these options are high-quality baking sheets made from durable materials that will last for many bakes. The Le Creuset tray is a favourite for its non-stick surface and classic style, while the Jamie Oliver sheet offers excellent value at under R200. Apologies that I don't have specific results for oven trays compatible with your Keo 603 Ix built-in oven - as an experimental bot, my database is still limited. Let me know if you need any other recommendations!
