I get mine on sale last year . what a bargain . great pix , versitile , & super bright ! we can watch it in the daytime it be so bright . I use it on the road for my show so it get use & abuse a lot . it be still run perfect on it be original bulb . when it be not on the road it be use as my primary widescreen tv at home . this unit will not show full the resolution of true quality hdtv , but do a excellent job . many hdtv signal have be downscale , upscale , dowscale again , recompressed , & reprocess so many time by the time it reach you home , most of the channel be not true hdtv quality anymore anyhow ... esp . signal through cable & satellite . I guess the FCC have not pass any law for hdtv quality yet . the unit have more than enough resolution for ordinary DTV & DVDs . for some reason , I do not get eye fatigue like I do watch other projector a few hour . the factory preset be not that good & seem to be for watch ordinary analog TV & VHS tape . fortunatly it come with 3 user settable preset with a very wide array of setting & tweak that make it a top quality performer . I buy the component input adapter for it from Infocus . the quality of the adapter cable be poor & pick up plenty of RFI . also after carefully unplug it only a few time , one of the connector fall right off the adapter . poorly , cheaply design adapter concider most infocus product be specifically design to be use on the road , set up & tear down easily & quickly all the time . the connecter for my other road equipment do not break after year of heavy use . fortunately for the road & at home the s-video connector do a excellent job . do not ever use the ordinary rca-jack style composite signal jack on a hi-end tv or projector . the signal will not be good enough . any good tv will just make the poor signal quality more obvious . the above reviewer must have get a bad unit or one that be bang around during shipping , or be drop . these be durable unit , but with too much bang around , you 'll have problem the reviewer describe . the grind sound come from the color wheel or blower fan be knock out of alignment . I also own they older lp-350 xga model & use a few of they other model . so far I be very happy with all of they I have use . although my very old lp-350 still work like new , I have do some mod on it & the lens to increase the contrast ratio , brightness & bulb life . I be surprised that if I can do it , that infocus do not offer a mod plan for they to do it for a price . they will not even sell spec & technical service datum on they old machine . I guess they want you to pay a arm & leg for they to do repair , or buy a new one . I have have to fix a few infocus projector out of warranty after they be bang around or just get well use & old ... with no help or sevice datum from infocus , even though it be request . fortunately , dlp projector have be around for a while now , so there be plenty of qualify tech familiar with they in just about every town who know how to fix , mod , & upgrade they at a fraction of the cost infocus will once they be out of warranty . from what I read in the past , you be better off send it to a local tech with experience with dlp machine for repair rather than back to InFocus . they seem to do a better job cheaper , & know what they be do . Infocus will not even to tell you where to get special tool need to take they apart . I wonder if they know how to service they at all . it be one thing to build one , but another thing to troubleshoot & fix 'em . I give 5 star for the product , not for the service , because I service all my own equipment so do not need they . do not take these thing apart yourself people unless you know exactly what you be do & experience . you can ruin or destroy they if you be not very careful & knowledgable .
