SF Elipsa vs Elipsa se

Has anyone had the opportunity to compare the older Elipsa with the newer SE model?
The older models are available for a discount now but not sure if the newer model is worth paying a lot more for.
Also, my room is quite narrow at 11ft and 22ft wide with a 7ft ceiling. But I have heard that the Elipsas work quite well in small rooms.
Any thoughts or experiences on this would be greatly appreciated.
