I use Ergosoft Staedtler.
I really prefer them to Prisma (I have experience with Prismas from art class. Not high on my list for colored pencils.). they're easy to blend with and give you a nice, soft texture.
I'm using them to color a picture right now, actualy. I'm loving the results.
I think it cost me about...23-25 dollars for a 24 pencil set. C:
