I am a fan of the Google adwords tool. I also use Market Samuri. Is there a tool where you can search keywords for number of monthly searches but you can input a list of literally 50,000 keywords and it will spit it out (may take an hour or two, I don't care). Google keywords tool only checks 100 at a time. Market Samuri can't handle lists this big. Any suggestions? Maybe something multithreaded that can use IPs?
