Thank goodness this is on a four cylinder. Changing the starter on a 616 is very quick, simple and clean and you can do it from the top.

A five cylinder OTOH is more time consuming and will sometimes require the invention of new swear words because the old ones aren't enough for the job.

As far as quality, you need a Bosch remanufactured if you want to have a chance for starter longevity. Before doing that, however, do a Voltage Drop test to make sure that the starter is getting full voltage. A few bad connections will cause the voltage to be dropped across the bad connection rather than the starter motor. Low voltage on an electric motor will wear it out fast.
