best current LCD's seem to be sanyo z4 or panasonic 900. Both around $2300.
see reviews at projector central.
For DLP's, check out new mitsubishi (model number 3000, I think) or the infocus 7205 (for about $3700).
Many factors to consider. 1) throw distance needed 2) light control in room 3) ceiling or shelf mount 4) size screen you want.
I personally think that if budget is a concern, you should probably get the panasonic as it will be several hundred under your top end, and you will need those extra hundreds for cables, install, etc, etc
