I like the epsons. i installed one in my works conference room last year and it worked very well for us. good image quality and very easy to mount

we have a small sony at work, does it’s job like it should and it’s pretty compact, if only they made nice, cheap led projectors….

it is also important to know how to shop for the correct projector for your needs…here is a good article on that

go with a company that has a good warranty, especially if the projector gets moved around a lot.

There are many, many brands and levels of quality (what kind of end user and application); I would suggest that if it’s a large-scale corporation and budget not withstanding, to go for high-end, but keep in mind that in addition to initial cost of the unit, you will have to budget for bulb replacement every 400–800 hours (depending on usage).

I would also add that depending on what your business is, you may not need a true “professional-strength” projector; for example, my college where I work uses very rugged, medium-quality projectors from Epson in their classrooms, but for the “board room” and presentation halls, they use Christie digitial cinema projectors-the ones used in movie theatres.
