Comparing to the w4r (not w30/40) overall including comfort, sound etc, at similar prices Nuforce Primo 8 ~$400. Both the Aurisonics Rockets (price appears to be going up $250-300) and RHA T10i ~$200 sounds promising with reviews and seem to be extremely durable, although I have not heard these two.
For my tastes, I find the w4r to lack highs and bass impact, there are other $100-200 iems that I find more enjoyable than the w4r, but are definitely not comfortable for me.
Although it probably won't happen with the Rockets and T10i due to being relatively new, IF you are in the US consider waiting for black friday in ~2 weeks time and see possible discounts on the Primo 8. Personally if westone offers the w30 for around $170 I'd go for those, the new westone line is extremely light and comfortable, also you know what you are getting yourself into in terms of the house sound.
EDIT: Spending $150 for a recable on an old w4 with no warranty, while you can get a pair of NEW w30/40 with 1 year warranty less than $100 more doesn't make sense to me.... Especially if you it's possible to get the w30 at $150-200
