Reviews of OEM Porsche timing belt

Like the 944, the S2, more specifically, they're finicky on timing belts and tensioners...I know guys that change them every 10-12K miles, or every 18-24 months, and they haven't had problems.
I want to avoid the Porsche engine because last time the timing belt broke it cost me $2000 to get things repaired. Plus I don't want to constantly be nervous about it breaking. It's not just the belt though - the Porsche engine is aluminum with free-standning cylinders, no liners, balance shafts which have their own timing belt which runs right next to the main timing belt, etc. Not to mention parts are super expensive.
