All right, people. Which (if any) of these options should I pursue?

I know I have to ride it to see if I like it. Just wondering if any of these are blatant rip-offs or blatantly amazing deals, since I don't know ****. Looking for something to commute pretty short distances with and do occasional longer rides on weekends. This is my first fixie, so I want to start with something cheaper and then if I like riding fixie, I may flip the cheap bike on CL and buy a Wabi Classic when I've saved up some money. Cheers.
