One question, are the brushes Kolinsky, squirrel or sythetic. I love their Kolinsky brushes, have a lot. But I didn't know about the double ended ones (not tempted though).
On the line of economic supplies: I just got three boxes of Roman Szmal Aquarius 5 full-pan starter sets from Artemiranda. At 13 € each now, I still find them great value for money, and as I enjoy color-mixing, love that they come with primaries, green and caput mortuum. Plus they fit inside a Barkley's (like Altoids) tin can and leave room for a small sponge and a Windsor and Newton tiny travel brush. Seems they are disappearing or becoming difficult to come by lately.
