I have some of the Knitter's Pride Dreamz DPNs, and I really like them. I also have some fixed circs Cubics (from the same company, I think) and those are nice, too--especially for squares like me.
It would be nice if more LYS had a variety of needles to try before you buy. Of course, then needle manufacturers would lose money on those of us who buy all these different kinds of needles to test drive.
And reading forums like this don't help. They just make you wonder what you're missing and, thus, drive you to the distraction of trying yet another brand!
