Many people love their Neo. I've never had one, but can only say that as they are made for Iwata, rather than by Iwata - and from what I've read, they do not seem to have the same level of quality or longevity. So while cheaper, can be a false economy if you end up replacing it anyway.
The eclipse cs - while more money is - quality and performance wise - one of the best value brushes out there. It's versatile in that it can go from a 2 inch spray pattern for slightly larger areas, to fine lines when you get to know it. I've been using mine for almost 3 years and apart from the chrome wearing off in the cup, (which happens in many brushesand doesn't affect performance) I can't fault it.
It's good for beginners because it's easy to maintain (one piece trigger mechaanism, and self centring nozzle), makes learning easier, and the better you get, the more you can get out of it, so you won't immediately be needing something else. You might want something else Lol, but you won't need it.
