This is an affordable mount that is a popular choice for the 8350. Read the amazon reviews, tons of 8350 people have bought it, and used it successfully with the 3 legged mounting method talked about. Also, it's shown in the customer images. I just bought it for my own 8350, and it works great.
I just bought the Peerless PRG UNV for my Epson 8350. Thanks to your question and the links. I had been looking at several mounts and another Peerless was in my list. But, this one at ninety six dollars is perfect. A few reviewers also mounted 8350s. No tax, Prime shipping!
