I'm looking to get a rear rack. I want something cheap but will hold up nicely. I'm also concerned because the bike I have does not have any attachment points or holes in the frame in the rear to attach one to. I just got a Huffy Concours Professional. Is there anything specific to look for in one? I'd mainly be using it for riding around campus and getting groceries home.

Also I want to get two water bottle holders for it, but there aren't any mounting holes in the frame. I saw one holder that you could wrap around the frame, but it was about 3x the price as any others.
