I would suggest you consider:
Does the site you are considering being listed on only quality sites controlled by human editors?
Do you understand basic link exchange etiqutte?
Will you link back to your link partners without playing games such as the use of nofollow or removal of their link right after you agree to said link exchange?
There are now hundreds of sites that list sites that participate in link exchange. Look for sites that educate the end user about relevant link exchange.
I was continually bombarded with sites that totally ignored my link criteria.... and this was one of the so called more professional outfits. It turned out the focus was totally on link volume, not quality. A total waste of time and effort.
Expect to be flooded with link requests from MFA and pure affiliate sites.
 If they have filters, only pick the exact categories that complement your site;
 Do not be tempted -- reject everything that does not meet your own stringent criteria. Pretty soon your ratio of rejections to acceptances will make it obvious that you are not interested in anything even remotely irrelevant.
BTW, with me the jury is still out as to whether it did any good -- I'll give it a little more time, but not much.
