I hear good things about Neuvation. Good value and he stands behind his products. I haven't used them personally, but I have a friend that rides a set of his wheels and he has nothing negative to say.

The Wheel Masters are heavier because of the the hubs and because those hubs require 32 spoke count. Likely to be super durable, but I know nothing about the build quality.

I've build 5 sets of wheels with A23 rims and I like them. That's in contrast to what some others on the 41 have experienced.
