Considering buying my first projector to use for v4 visuals. I want something that is bright, easy to use and can project well in a small space (I would mostly be doing visuals in office/store/club environments. Seems like I need a short throw projector with 3k+ lumens and 720p+. Any advice from you guys?
That sanyo 4500 lumen LCD will be great if you perform with a lot of ambient light. If you anticipate performing in dark environments, a DLP like the optoma you chose will have deeper blacks. Also most DLP projectors have a sealed light engine, which means no dust can enter and dirty up the image. LCD systems are not sealed and seem to be a bit more fragile. You do get better brightness with LCD projectors in general, though.
Also make sure your computer can handle outputting the native resolution the projector requires. I sometimes have to dumb down my show to run on resolutions like 1280x800(WXGA) when I design for my projector at 1024x768. If you are running a lower resolution backbuffer to compensate, you might as well have gotten a lower cost/brighter/lower resolution proj.
That Sanyo looks nice though, although you might want to look at something with a zoom-able lens for more flexibility (if you care about resolution).
I’d look at 1024x768 projectors too, unless you absolutely need the high res.
sanyo is well worth the extra buck atop any other consumer brand because air ventilation is usually much better than that of the rest of the field. a manfrotto magic arm is something else you should consider from the beginning if you want flexibility in a lot of environments.
