Quote: +1 to that, or sell it for about 50$, or lens it to your kitt/grandkid/newfhew/niece so they can learn.
Must be lucky to get $50. I bought it new in December 2010 for €49 (many German shops made a sell-out because of the 18-55/II). I was very lucky to get €38 on eBay when I replaced it by the WR version a year ago. I don't think I would get that amount now.
But I was quite satisfied with the lens at that time and replaced it only because of the WR to be used as the standard lens with the K200D, which is also WR. I think with 10MP any difference is not as visible as with the 16MP of a K5, with any 6MP (K100, *istD) it is probably everything you need. Unfortunately, most owners of these cameras will already use it.
EDIT (Correction): I bought it new in
December 2009 for €49
