I am wondering what you are doing to your lenses that they break down so often. :-)
Of course, we can't judge the long term durability in our reviews. We can only comment on the mechanical construction out of the box. However, and that's where Tammys were not the best, the centering is usually worse than the (true) average. Part of the reason for this is also the higher than usual use of plastics in our opinion. Of course, this is no reason per se. e.g. Tokinas use much more metal yet their centering is often worse - which probably relates more to sloppy assembly.
