Nice selection.
I used to pick up most of my acrylic paints from wholesalers and art shops. It was some time ago, but I was getting 60ml bottles for about 70p a bottle, which was generally a considerable saving over those from 'the brand that shall not be named'. However, given that I haven't actively painted for some time, I'm sure that they'd all need a considerable shaking before they're used. Having also bought (a few) of 'the brand that shall not be named' paints, I can say that the quality of 'the others' stood up well to comparison. For solid and metallic colours the art shop is the way ahead, but generally the washes from 'the brand that shall not be named' seemed to be better than those from competitors.
Out of interest (and want for a trip down memory lane), I just looked in one of my paint boxes. I found nearly four dozen big pots (59/60ml) in there, from a variety of brands: Grumbacher, Anita's, Folk Art, and Accent (of course, I've no idea of whether any of those brands are still available). On top of that, there were probably a couple of dozen smaller pots and a few tubes too!
