I'm after this one. http://www.bestbuy.com/site/Canon+-+...&skuId=9065174

I need a good walk-around lens for trips that are not dedicated eco-tours such as visits to cities but with enough reach to still capture local birdlife in parks. I have a 18-135 but could use the extra reach of this one. I may also get a teleconverter to further extend it.

Best Buy has a price match guarantee so if B&H comes down, I can get them to match it.
