That's a great idea, I never would have thought of that

Actually, I'm looking for specific brands and model numbers that have been successfully used by someone who owns this projector. The Sharp website and owners manual state that only the Sharp AN-3DG10 glasses are compatible. Since Sharp sells these glasses for $150+ through their website, it's no surprise that they don't mention less expensive alternatives. As far as ebay is concerned, the only glasses with that model number are currently selling for $145.99 + $15.00 shipping, which is not exactly what I would call a "good deal".
There is an article here (
http://hometheater.about.com/od/televisionproductreviews/fr/Sharp-Xv-Z17000-3d-1080p-Dlp-Video-Projector-Product-Review.htm) that mentions the XpanD X103 Universal 3D Glasses as being compatible, but even the XPAND website doesn't list Sharp Projectors as being compatible. I have read that the Sony PS3 3D glasses are compatible with other IR projectors, but there's no mention of its compatibility with the z17000, specifically.
Since this is the official Sharp 3d xv-z17000 owners thread, I was hoping that there might be someone who knows a more affordable brand/model of glasses, and who would be so kind as to provide a specific recommendation. Needless to say, I would greatly appreciate it.
