Greetings, Regarding the "e" version. Obviously wireless can be very handy, especially if you have to open walls to run HDMI. I've used the 5020e with and without the wireless. Here's the downside to wireless:
As you have certainly noticed any Blu-ray player is constantly changing bandwidth and resolution as it cycles through putting in the disc, previews, menus, and primary content. With most projectors or LCD TVs and blu-ray players, all this switching can sometimes take 5-10 seconds before something ends up on your screen other than resolution messages, play button icons, source identification, etc.
When you go to wireless hdmi, that process slows down. You have far less idea of what's going on as the blu-ray player and projector communicate. Some of those visuals never show because of theadditional delays in establishing the changes over wireless.
I believe the bulk of all this mess and delays is the fault of HDCP protection, but let's just say you are in the dark, longer, with wireless. As long as your are patient, and have a solid setup (In my case very solid, I have only about 15 feet between 5020e projector and transmitter, it's really no problem at all.
But I'm not that patient, so, since I rarely need to use wireless (only if I have two other projectors running at the same time, I prefer to use my cabling. Again, this issue is not Epson related, but rather wireless HDMI / HDCP related primarily. If it can save you a bunch of money (wiring) or have another compelling reason, go for it. Otherwise, life will be a bit simpler with cables. Hope that helps. -art
