Guest blogging is too much work for one link. If you're going to get traffic it's worth the time and effort.

Guest blogging is a great way to tap into another blogger's active audience. You should probably make sure that their audience is also your target audience. It also helps if it's a very active group of people. I've noticed that some "blog communities" are very involved, commenting on posts and talked amongst each other within the comment sections on the blog, while others don't have that kind of commaraderie.
In those cases, you'd probably get more traffic/sales from a more active blog. Those people trust their blogger and will therefore trust you as well.
