Amazing projector. I run it in a lounge with tons of ambiet light and it STILL gives a bright, beautiful picture. One of the best 3D projectors on the market. Highly rated and reviewed. About 3 months old. Less than 600 hours on the lamp. Runs very quiet.
If you only get watchers maybe the problem is that your asking price is too high. Or there's just not enough demand for a second hand projector of the sort you're trying to sell... so people will be expecting to pay what they see other second hand projectors, much less fancy ones than yours, go for. Claim it's designed for Mac or something, people pay crazy prices for 2nd hand Apple hardware on trademe.
