I'm glad I looked at your location...my answer would be different for points north! LOL
Are you always out and about? I'd recommend a baby jogger (i have a city elite) or a BOB. Those are heavy-duty, off-road types of strollers. I have a baby jogger single and a BOB double.I use both. :) If you use public transportation, I'd change answers to a lighter duty umbrella stroller. Also, with better strollers, resale value is pretty good. You can probably also find one on craigslist that is gently used. I think strollers are like anything else...you get what you pay for, but of course everyone has different wants/likes. I'd test-drive a few.
In the beginning a snap-and-go isn't a bad idea, as they're cheaper than most of the adapters for the more expensive strollers, but honestly they're good for mall walking and not much else. Nothing wrong with going to a store to test-drive and see what you like best. Also, another thing that I thought about was if I'd be having another child relatively soon. I looked at Phil/Teds and other double conversions, and thought that the best solution was getting a separate stroller later on that would give me the freedom of having a single or a double at my disposal, and that could handle taller children side-by-side.
Hope I clarified rather than confused the issue.
Congrats, and let me know if you have any questions.
