Digitap projector of iPad2 recommendation

[anonaboat]

Ooops! DIGITAL projector...I know there are pits and pieces of this topic within the forum but let's get focused here...Question: who is using which specific digital projector with their iPad2? I've been using a friends Optima EP771 for my non-profit's iPad Keynote presentations. It works great but I think our friendship might be wearing rather thin with my over use. Ergo, I'm on the hunt for my own machine. Price is an object, but so is brightness and throw distance (20-30 fet needed). Comments? Suggestions? Recommendations? Thanks, BJ
