SerpBuddy, which is the best I've used ever and had it a year $30pm, but too often it hasn't been updating. I do contact the guy on BHW to tell him to sort it out probably 2-3 times a month, but I like it as it's web-based.
am I the only one who use accurate monitor for search engines? it's not free, but you can download a trail version and writing a honest review about it, to get a 1 year license. it's a desktop app, works for me, it also shows the first xx page of serp (according to your setup) so you know who is ahead of you
