I purchased a set of integrated turn signal mirrors from d2moto relatively cheap (about $30 shipped). So far they work good. More vibration than OEM mirrors, so I have to adjust them every time I hit a big bump but they upgraded the leds so they are noticeable during the day and bright at night. I've had them for 2 months and so far I am satisfied.

 

I've just bought cheap aftermarket (not integrated however). Like nicos said ^ a little more vibrations, but nothing I can't use/live with.

I use the stock mounts, and just grind the stalks, works great.

Another temporary fix is just to run one mirror. Most states only REQUIRE one, if any at all. So just look into your state laws.

 

As long as you have one your legal just take it off till you get a new one, I rode with no mirrors forever and never had an issue.
