I am sure they aren't the best, but every review of them has been very happy customers. With my relatively low expectations I am sure they will exceed them easily.

Riding at a bike shop should get you a pretty good idea of what you are looking for. What Craigslist area are you looking at? I am not familiar enough with that area to know for sure where to start looking. You might get lucky and find someone that is selling a bike that includes some of the accessories you need.
