I have a German made one that is now about 5 years, and 4000 rounds old. Purchased new from European Arms in North Vancouver, added trijicons and a Hogue grip (I have long fingers). Otherwise stock. Mags are in the stratospheric cost range (+/- $75 a piece).
Quality wise, they are outstanding. I would happily carry this pistol, if that was an option.
I grow weary of the TDA, however, and am considering a striker gun... Having now used a DAO pistol at work for over seven years, I have grown to like the consistent trigger pull, and lack of an extra control on the pistol.
YMMV.
