Belt tensioners last around 100K miles on a W124 (300E series) car. Maybe a little more, maybe a little less. Maybe a lot less if car wasn't maintained well before you bought it.
Parts (if you buy them from PartsShop) run around $325 (I did mine around 1 1/2 years ago) and the labor took me around 3 hours one Saturday.
My mechanic charges around $475 for parts and labor. If you're REALLY comfortable as a mechanic and have a BUNCH of good metric tools, give it a go. If you're not, PAY THE MAN. Also, spend the $30 or so and replace the belt at the same time. IT DOESN'T MATTER WHEN IT WAS LAST REPLACED, DO IT WITH THE TENSIONER.
