Since Colm seems to have already answered everyone's recent posts, I'll just add a few notes. Thanks Colm!

But some companies, including Gefen, use the chipset in some of their HDMI extenders.
I do wish this would take off. It seems to be the "thought out approach" that custom-installers and enthusiasts alike would faun over. Alas the "best" solutions aren't always what make it main-stream...
The other point worth mentioning here is that Gefen extenders are not all created equal either. I am by FAR no pro on Gefen equipment, but being "this close" to buying some during this journey led me to reading all the forum posts about their equipment and I found far more negative posts than positive ones. I do realize people tend to get online more when there is a problem than when it works the way it should, but the sheer number of negative posts web-wide about Gefen equipment made me look elsewhere.

Some trends seem clear. Inexpensive unpowered or line powered devices seem to have a dismal record. Powered two cable devices seem to work for some but not for others. And expensive single cable devices seem to work quite well.
Interestingly it seems a few people had better luck with powered dual-cable extenders than powered single-cable extenders. Since all we have to go on is their word, there's no way to judge definitively what is the "best" equipment for your situation. The "over-generalized-trend" however is as Colm mentioned-- single extenders seem to work better than dual extenders.
The bottom of the first post is intended to capture the test cases (and their success rates) of those reported to this thread to-date. Have a look there and see if anyone's configuration looks similar to yours. Maybe that can help guide you for the best place to start.
Other than that, just make sure you buy from a company that has a return policy, in case you need to try different solutions before settling on the best approach for your situation. Be aware that many online retailers now charge restocking fees even if returned in mint condition. Sometimes even if still in plastic wrap.
good luck, and report back what you try and how it works out!
