newyorkers: Dog (pet) carriers and strollers for NYC

What kinds of pet travel carriers do you have and how often do you use them in NYC? Have any of you gotten dog strollers? I need tips for selecting strollers and carriers.

I have been looking on eBay.com for different, inexpensive designs of dog carriers and dog strollers until I know what type of style/design is practical and comfortable (for me and the pup). Would love ideas for medium-sized dog under 20 lbs., with a long torso (dachschund, but I think ideas for beagles and other short legged dogs would be great).

For the last year, I have a Sherpa dog carrier to use whenever I take the trains and buses (required on mass transit). Over time, I find the rectangular-shaped carrier rather bulky and awkward when I have to move him frequently. Also I am strongly considering getting a dog stroller since sometimes I like to walk long distances, or go in some retail stores that allow pets only if in a carrier (or fully-enclosed stroller compartment).

These are a couple samples of each of the strollers or tote-style carriers I am considering.
