When large price reductions come into being, it always seems to suggest that particular model is destined as 'old' because new is due as a replacement.
With Argos, I tend to find that their pricing can be a little confusing, especially on their 'previous sold' explanation on some mark-down products.
The FE is a Toshiba man, so he might have some advice available. We have a Toshiba microwave, which is a vintage model, and still works perfectly today. Cannot ask for better than that from a manufacturer.
