Generally, the belts that I have seem or heard about breaking didn't really break in half, but more stripped a tooth. This as you know causes the timing to jump and depending on how many teeth stripped obviously will damage an interference engine. The choice is to either get ripped off and change your t belt every 90K miles, or roll the dice and risk $4K engine repair. If you keep your car a long time it might end up costing less in the long run to just wait until the belt breaks and either swap the engine or have it repaired, but that is a lot of down time for some people and an all at once cost. $1200 every 90K miles seems to be insignificant too me in the long run. But, that is just my perspective. If I had a non interference engine I might wait until the belt breaks. Then you just need to replace the belt and readjust timing.

If they do sell them separately I have access to a hydraulic shop press and have replaced bushings before a few times so bushing replacement would be no biggie.
