I have a Sony 10HT and have been real happy with it. Make sure you check the hours on the unit, a new bulb is about $450. Also, look for stuck/dead pixels. This is one of the issues with LCD projectors. Otherwise, if all checks out good, that is a great price for this wonderfull projector.
Your best bet is to go to theBigPicture forum and post a question regarding possible issues with the Sony 10HT in its dedicated forum. For $1000 I would buy right now even with no lamp! But better check for dead pixels and the hours on the projector itself.
