I found the 18-135 for $105, without mold. Seems like a good deal, but I am afraid of regretting missing the wider zoom range.
The wide zoom range on super-zoom lenses comes at a cost. Generally, sharpness at one end of the range - sometimes both - is compromised. Even if centre performance is good, borders and corners usually fall well behind expectations from shorter-range zooms. There's usually quite a bit of distortion too, some of it complex.
I owned the DA18-270, and it's not a bad lens - but it's not
great at the long end, never especially good away from the centre, and - like most lenses of this type - it really needs stopping down considerably to be fully useful.
If you're intent on owning a super-zoom, consider Sigma... the 18-300 C is very good considering the range. The 18-200 C is better still, but obviously you give up some reach at the long end.
I have more than enough lenses, but I'm often tempted to pick up a used Sigma 18-200 C...
EDIT: If you should decide to buy the mouldy DA18-270, bear in mind it has 16 elements in 13 groups. If you need to remove anything other than the front and/or rear elements, good luck. It'll be one heck of a job
