Okay.... so my iwata buy didn't work... so that aside, what to buy?

I was looking at luckymodel and saw their sparmax DH-2
here

I have a good airbrush for coverage etc, and details are good, but i want something double action, top feeder, and double action that can pull of nice detail work. would this do the job?

Anyone recomend this? I've got some money to spend on other things and iam wondering weather to buy a new ab now or later.
P.S.--- I spray acrylics mainly ( tamiya)
