Well too late anyway, I'm pretty sure Santa is bringing me some.
What is your experience with other paints? I have only used M Grahm so far and see no reason to change. I'm tempted by Old Holland that everyone talks about as being the cats pajamas. I haven't seen them to be all that expensive either.
I can't speak for M Graham as I haven't used them but I tried Winsor and Newton, Gamblin, Daler Rowney, Art Spectrum, etc, but as soon as I squeezed a tube of Old Holland I knew they were different, thick from the high pigment load, very mature, intense colours. I like my paint on the thick side so they appeal to me and also inspire me.
They cost a bomb down here, about $70.00 Australian for a 40ml tube of the cadmiums, the others aren't so bad. It's subjective of course but I think they're well worth the money. If they're cheaper in your parts, give them a go.
Yes the cads are extremely expensive. I avoid the cads for that reason. So far I see no need for them.
