Which Utilite hardware for Volumio?


I’m really excited to have found Volumio, it looks to be a good solution for my first step in to digital music. I like the Utilite, could you offer advice as to which model I should select, and as it looks like they pre-install s/w whether it should be pre-installed with linux, android or nothing?

Also, I’ve been hunting for some images of the volumio webui, could you provide some on the site please, or did I miss them?
I’ve seen sound@home on google play, which looks ok and functionally seems good, but I’m also interested to hear of other UI options if there are any?

Many thanks, can’t wait to try it out.
