I love my BOB! Granted it is a single stroller, but for running there is nothing else better on the market. I usually run about 4-5x a week 3-4 miles at a time and he BOB is super smooth and I can literally maneuver it with one finger. The sun shield is extra long so my LO never ends up being blinded by the sun. My sister in law has the double and pushes her 4y.o and 15month old with ease. I have tried hers and it is just as easy as the single. A lot of the other jogging strollers have a fixed front wheel which is a major pain when turning or even veering to the right or left. If you go with the BOB make sure to get the Revolution with the swivel wheel. It is a few bucks more but TOTALLY worth every penny. Also the seats are adjustable to sit up or lay back. Happy Jogging!!!!!
I thought about the craigslist gig too but I ended up going with a new one. For the price that people want for one you really could almost buy a new one. Amazon has good deals if you get free shipping but youre out of luck if something breaks within a week or so. I got mine from REI. They have pretty good sales sometimes and if you join their co-op (for only 20 dollars a year) you have free maintenance on all equipment you purchase from them, and you get shares of their stock which you can use for more gear or cash it out for the money. Its a pretty good deal. The strollers have a great track record but I just like the idea of having some place local to return it to if something breaks. As for waiting 6 months, I had my DS in mine at 5mos old. I just secured him with a few blankets to make it nice and cozy. The seats are really deep and very safe. It was a bit of a strain on the pocket book but it is a stroller you will use for years and as you can see on craigslist they have a good re-sell rate.
