Graham,
Even if your church doesn't have a lot of money, make sure you do your homework before taking this big step. Get all the info you can.
You may find this helpful in your information gathering:
http://www.fowlerinc.com/contact/packet.php Fowler is a good, reputable company who knows and understands the needs of churches.
One thing I would strongly suggest is that you TRY the projector in your church before making a commitment to buy it. When we installed our projector at our church, the company we purchased it from brought it in and demoed it for us to make sure it would project a strong, clear image in full-lighting conditions. You don't want to have to turn out the lights or dim the lights every time you use the projector.
Another consideration is your projection software. We have been using 'Easy Worship' for the past several years. It is an extremely easy, user-friendly software for worship song projection. You can go to their website for more info and even download a demo -
