As you know Shawn I have often had to choose a bike based solely on pictures and the poster's description. The OP should go check them out in person, there is no magic thing that tells you what a bike is like from a picture and I always expect to work on my bikes some.
A picture won't necessarily tell you what condition a bike is in and price is just a number. Look them over and get the one you like best.
It's not different than any other mechanical thing, car, cassette deck...
