It depends what you want to do. I have a torpedo with low lumens for my singing pumpkins. It is visible after dark but not during twilight. I have a 747 and we love it. I have the one with the MH 150watt bulb. they are very cheap, 15.00, abd last for over a year of cartoon viewing at my house. It is not super high quality image. SVGA Looks better than vhs but not HD. 800X600 1500LUMENS. Works great for smaller images or ghostly bigger images. I think it is pervect for the price. If you can afford XGA with 3000 lumens all the better. If you want ghostly images cast on walls or windows try the fresnel lense set up with tube tv's from thrift stores. They are now about 20.00 tops.
