If you seriously thinking about CIEM, you can look around the JH5pro! (in the price range of W4r) Am thinking seriously buying JH5 now, or waiting 6-8 months, to get JH13!!
Take a look at this stunning reviews/posts! http://www.headfonia.com/triple-jh-comparison-five-ten-and-sixteen/3/
The JH5 is a great entry level ciem. I heard the demo and it think it is better than any of the Westone and Earsonics TOTL universals, albeit a slightly different presentation. I had a friend telling me how good it was for a couple of years and never took him seriously until I heard the demo myself.
On another site, the virtues if the UE4 have been praised recently. I haven't heard it but it reads like a great deal too, especially if you want something on the neutralish side.
