Abe, the E-50 was disco'd about a year to a year and a half ago. It was the "budget" version of their "sardine can" Xplora model built into a "standard" chassis. While the Xplora had remote capability, the E-50 doesn't ( as far as i know of ). I think that they did this to encourage you to spend more money and get the Xplora ( which was probably much higher profit unit ).
While i haven't tried the current Musical Fidelity offerings ( that do offer remotes ), someone else that i know ( from the net ) did and was not happy with it. Don't know if it was a matter of system incompatability, personal taste, lack of performance at that specific receiving location, etc... I will say that it is similar in performance to most English tuners, they lack sensitivity. He ended up replacing it with a more expensive Magnum from what i can recall.
If you look around on the web, the E-50's will pop up from time to time. I just snagged another one for my Dad for under $115 including shipping !!! Needless to say, i couldn't pass it up. They typically sell for about $250 - $325 from what i've seen. Not saying it is the best you can buy, but i've found it to more than hold its' own, especially at the prices that i'm talking about.
