Summary: Personal Experience Excellent used projector value. Image quality is superior to many of the newer projectors on the market. Lamp life may be a problem according to other reviews. I bought my unit used on eBay with unknown hours and got 1700+ hours before the lamp finally bit the dust. I can't complain about that.
Summary: Personal Experience I bought this projector for use at work for powerpoint presentations and showing videos. It has a good picture but is quite noisy and gets very hot, anyone sitting near it is in danger of heat stroke particularly in a small room. The built in speaker is not up to providing the sound for videos, external speakers will be needed. It is easy to set up and get going and the remote is better than other projectors i have used.
Summary: Personal Experience I purchased the Infocus LP340 primarily for home theater a few years ago for around $2600. It is awesome. 1300 lumens is nice and bright. Projector is simple to use. I have had none of the bulb problems people here have reported. Maybe that is with later models, or if you are buying them used for under $1k, well, they are probably problematic projectors. The size is perfect and easy to set up.
Summary: Personal Experience I bought this projector as a reman unit about 1 1/2 years ago. I bought the 340 instead of the 340b because of the lack of the HTQ software and the DVI port not on the 340b model. The picture quality has been great, colors are very brilliant and the brightness is good. The dirty light or halo is apparent but can be eliminated by placing a black boarder around the screen.
Summary: Personal Experience The image is of good quality and brightness. Problems The problem is premature lamp failure. To date, the unit has used 3 lamps counting the original. Yesterday the lamp failed. Estimated lamp hours is 400 or less each time. Received back from Infocus repair facility in Feb. 03 where they replaced the power supply, lamp, and cleaned as part of warranty repair.
