DA* 16-50 or Tamron 17-50

A store in my area has a new tamron and a used DA* they are both on sale for ~470$ (very uncommon in Israel)
I want to buy one of them and the last time I took a look at the DA*' it malfunctioned (when it was on my K-5 showed "low battery" and then power off) and now they are having it repaired (they side it was SDM).
and so I don't know witch to get...
What would you do?

i've owned both, the one i've stuck with was the tamron. in short, if you shoot jpeg or prefer minimal RAW post processing work, need WR, love "pixie dust", enjoy handling really well-made lenses and shoot for web, go for the DA*. Its just a sort of magical kind of lens.
If you don't like flare, want something sharp and don't mind plastic, go for the tamron. its the more technically good of the two

I know this comparison but it doesn't answer the reliability question and add to the equation that they are at the same price (used DA*)...

Unless the slight coffee-grinder noise of the screw focus would be a problem for you,
I would recommend the Tamron, particularly if the guarantee offered in Israel
is comparable to the 6-year guarantee offered in some other markets.
Although I'm not a big fan of zooms, I'm happy with my Tamron 17-50/2.8 A16P.

as long as SDM function and you are willing to pay the extra (but seems you can get both for same money)
I recommend 16-50. it is overall better. lens is not just about sharpness. but if you only focus on sharpness, tarmon is better.

I really like my Tamron 17-50. I had to dial in a -5 AF adjustment on my K-r but after that it's been great. It's not quite as sharp as the better prime lenses but still very respectable.
