Thanks Emporium and NBS. Appreciate it! So it looks like the SE would be 4GB DDR3. I currently have the xrs4000 and based on his budget I was going to recommend either that or the E2 SE. He's just going to use it mainly for the buzz tv 5 app (live tv, vod etc) so I think he should be ok going with the E2 SE since it's a newer model.
