I've heard pretty good things about this tool before and I just got an email to say that Appsumo are doing a deal on it - for the next 24 hours they are $39 for a LIFETIME 'Plan A' account. Thought it might be of use to some people? the site is a bit confusing - the link opens to a email sign up page but just ignore that and scroll down to get straight to the deal. Linky: http://www.appsumo.com/~jQ42d/ ps. I don't work for Appsumo!
