Stay clear of Emma Lasers. From what I read elsewhere, they have been selling a high quantity of counterfeit pangolin products. Pangolin are preparing a lawsuit towards China sellers. Agree 100% with Brad. Save up and get a proper projector. The ultra cheap Chinese boxes will not last long and they have very limited second hand value. A proper projector is easy to sell second hand.
I also bet you will regret not having a DAC and software at once. The build in effects are extremely limited compared to using a computer controlling the projector.
All written above are personal experience. Learned the hard and expensive way.
