Hi H.,
My painter/foreman has always used Dunn Edwards. He explained to me why he likes this paint~ one reason is because it does not have lead in it. The coverage is fantastic and they have so many wonderful colors from which to choose. We've always used this paint also and it's really very nice. It lasts a long time and it is easy to clean. If you get the color card of the Mythic you mentioned- the color green you really, really want, Dunn Edwards can color match it for you and they are also superb at doing that. I have a red in my kitchen that was color matched from a Ralph Lauren that I liked a lot. Try that!! You can color match anywhere.
If you are also in need of a painter, I have the best referral you could ever find... and another one after that... I was thinking that perhaps my first referral could help you out and pass on his discount for the paint to you... of course this is all something you'd have to work out with him, but he does such a clean-cut and fantastic job... I actually need him to repaint my house inside again soon. Everyone I know for whom he has painted over the years has felt the same as I- that he's exceptionally clean as he performs his work, he's honest, he's easy to talk to, he's nice to be around, he's very professional, his prices are great and fair... I think he can even show you pictures of his work- it's immaculate. Anyway, it would be great if that discount of his would work out for you :). Let me know and I can give you his number and talk to him for you.
Good luck!
J.
