I haven't done monograms via projectors yet, but definitely will consider it. Mostly used for Wedding slideshows and corporate presentations. When hired for use at a wedding, I love to do music videos.
Both are short throw and available refurbished on e-bay - Benq $697 - Optoma - $799
While I don't like the idea of refurbished, the price difference is almost double for the benq. How anyone still claims to have new models since it (benq model) was discontinued 2 years ago is beyond my understanding, unless they are non-US versions.
The new Benq model is the MX822ST and is $799 refurbished (one year parts and labor warranty). I am thinking I should probably go this route.
I have the two NEC NP60's which I guess I could use for Monograms since they are not short throw, and was considering selling, but they don't have much of a resale value.
Where or how do you place the projector to do a monogram, without getting the stand in the way or guests walking in front and obstructing the image?
