Saw this on AO....a bit more expensive that the K-Mix models on Amazon, but 1400 motor (compared to the 500w), more options to upgrade with add-ons, and a titanium model which gets some sturdier accessories.
"With a powerful 1400 Watt output, this Kenwood Stand Food Mixer will combine even the toughest ingredients, making cooking and baking simple. As this model is a stand mixer, it’s easy to use on kitchen worktops, for quickly and safely whisking egg whites or mixing cake batter. It’s also really versatile, as it comes with 3 accessories – a dough hook, Kenwood’s ‘K’ blade and a whisk – perfect for all your baking needs. All the attachments are also dishwasher safe, so you can easily clean and maintain your mixer."
