Advice for blurry Canon EF-S 15-85mm

I would like to ask for advice. Short background story:
In June 2010 I bought Canon 7D and Canon EF-S 15-85mm f/3.5-5.6 USM IS. I used the lens for about half a year and found out that right side of the photos was becoming more and more blurry. In March 2011 I sent the lens for repair and got it fixed. One year passed after repair and I noticed the same thing - the right side was becoming more blurry. There is no difference between phase AF (regular mode) and live view mode. Both of them produce the same result. The blurriness is mor noticeable at f/4-f/5.6 aperture. I have no complain regarding the left side and the central parts of the images.
There are several variants:
1. My lens is defective from the beginning and the repair service just temporarly fixed the issue.
2. Something wrong with the design of the lens
3. It's just an minor accident and my lens can be fully repaired for the rest of the life

The lens is out of warranty and, as I understood, the fix at Canon service will cost me at least $350-400 (repair service, shipping, insurance, etc).

Guys, does it make sense to send the lens for repair or throw it into trash can and forget about this ill-fated Canon lens? And look at Canon EF 17-40/4 or smth like this for everyday zoom?


PS. Question to Canon staff: have ever heard about any design or quality issues with EF-S 15-85mm f/3.5-5.6?
