Sony W10HT and Sanyo PLV60 can be had for $4500-$4700 and they are native 16:9 LCD projectors with good reviews (check www.thebigpicturedvd.com/bigequipment.shtml for reviews). You can also go for the Infocus LP530 which is a 4:3 XGA DLP with 2000 lumens. The Sanyo LCDs like the XW20 or XP18N may also be close in your price range.
