Looking at an Amlogic box eg S905 to run Openelec, what do people recommend?

I love Openelec, it's brilliant, hell I've even donated to it.. it's the ultimate media player as far as I'm concerned.

Traditionally when setting it up for friends of mine I've used an Intel NUC, however recently I've discovered the Amlogic S905 etc based machines.

I believe there is a version of Openelec that'll run on them. I'm not talking about running Kodi, I'm meaning have a box that'll boot directly to Openelec and forget Android.

So my question is what's the best box that Openelec will run on? eg a S905 or S912 etc?

What's the best version to use?

Thanks
