About a year and a half back I evaluated a couple of search engine rank trackers and compiled a list of decent softwares (preferably web based) available. Today I feel like posting the list on this blog for reference purposes.
Pricing: Free/Paid (1 time payment)
Pretty good desktop based tool. Has restrictions in the free version like not allowing saving of projects, exports, etc. which means better to go with the professional or enterprise versions.

SERPFox, MicrositeMasters, SERPBook and AuthorityLabs
All paid solutions with micrositemasters being fairly cheaper and with more recommendations from the SEO community (google search).
I personally used AuthorityLabs for quite some time.
Currently they have a product called PRO that can be tried out for $99/month (will later get merged to this new product with all the data imported).
Loads of negative reviews can be found though.
Neat Firefox plugin to facilitate the task of checking keyword ranking for a domain on Google, Yahoo and Bing.
SEO SERP Workbench
Its a chrome plugin, atleast helps make the process of checking manually much quicker.
Here’s a big list of rank trackers.
Feel free to mention any other good tools that you know of in the comments.
