I paint a lot of stuff, and so am always on the lookout for modestly priced brushes that are good enough for the sort of work I do.
£10 for 20 brushes counts as better than a bargain, at least if they don't fall apart after the first use. The pack came from Brushes 4 Models at the garden rail show recently. The make normally serves the art market, but also takes space at a few model railway shows.
I've been using a both pointed and flat versions for a couple of jobs recently, and am very impressed. They have been cleaned many times and held both acrylic and enamel paints - and yet have held their shape and the attractive colouring of the bristles. I've certainly spent more and enjoyed less impressive results.
The only problem? Brushes 4 Models doesn't have a web site, so you need to keep an eye out for him at exhibitions, but if you do, grab yourself a bargain.
