The most important thing is going to be the quality of the build. But I have know experience with Neuvation or Wheel Master so I can't comment there.
But personally (and depending on your weight and riding conditions) I would look for something that split the difference like these:

If a few extra grams don't matter to you, I would want more spokes than the Neuvation, and I like that the set I sighted uses a common Sapim spoke and brass nipples all around. It should be durable but easy to find if you did need a replacement. The Wheel builder models uses a straight gage spoke which are cheap and heavy. Double butted (like the Sapim Laser or DT Competition) are lighter and at least as durable for very little more $ so I would look for that. Shimano hubs other than DA are high spoke count so it should be a durable and easy to true wheel, but it obviously adds weight.
Neuvation uses Novatec hubs although I don't know if they are the same model as what I linked. But Neuvation makes a pretty good hub for a cheaper import. It is lighter than the Shimano because it uses an aluminum freehub body. It also has cartridge bearings in lieu of Shimano's loose balls which usually means less servicing but more expensive replacements when necessary.
I would recommend adding ~ $100 to your budget and getting a handbuilt from a Psimet or other known builder with the Kinlin XC279 laced to neuvation hubs with 20 or 24 front spokes & 28 rear Sapim or DT double butted spokes. It should make for a set of wheels that will roll smooth and true for a long time making the extra cost more than worth it.
Or, order the parts from the bikehubstore and Bdop and learn how to do it yourself.
