Fat Lama is a rental site, so it doesn't sound like it is for ownership. Just a one and done scenario. In which case, it barely matters. I do agree that a short throw doesn't make a lot of sense though. Even going beyond a 1024x768 projector may not matter if it is just photos viewed under non-critical conditions on the side of a house for one evening. Lumens matter though as well as the size someone is hoping to get. And, I would stick with LCD as you will get more lumens out of the projector. I would probably want a 4,000+ lumen projector though for a punchier image. Also something with decent contrast (1,000:1 or better typically).
