Get it while the rebate is still in effect. I found one at a local dealer that was older stock, so at a cost previous to the price increase. That, with the rebate and a trade-in (try and do THAT with an online store) allowed me to pick up the lens very cheaply. Cheaper than used in fact, for my first ever new Leica lens!
Yep, it's super sharp, compact and very flare resistant. It's a perfect outdoors lens.
