I bought my first-ever slow cooker a few months ago, and decided to start with a cheap one, because I wasn't really sure how much I would use it. I went for the Cookworks Signature (3.5l) from Argos. It's shown in the catalogue as £19.96, but it was only about half that price when I got it.
I've been delighted with it
I've just had a look on their website now and can't actually see the exact same thing. There's a cheaper Cookware model at around £11, and there is a bigger
one (6.5l) at half price - £14.69.
I'm not usually a fan of Argos' cheap 'cookware' range, but the only slightly negative thing I would say about this slow cooker is that the lid doesn't seem to fit perfectly, but surprisingly, it is working perfectly despite that, cooking things well within the expected time.
I haven't regretted my purchase once
