I wanted a sling style bag with an option for carrying a tripod.
That left me with the Lowepro 102 or 202 AW, the aforementioned Case Logic which lots of folks seem to like, and another Case Logic sling I stumbled upon by chance.
Ultimately, I bought the OTHER Case Logic sling bag (DCB-308). Bigger than the more expensive Lowepro 102 AW or the Case Logic SLRC 205. Probably about the size of the 200 series Lowepros-- a good compromise between size and carrying capacity. It can fit a DLSR with attached lens, and two long zooms in the main compartment comfortably. Comfortable to wear, well designed, and includes an attached rainfly.
