Domain Research Tool http://www.domainresearchtool.com/ This domain tool is the the best kept secret of the big players. If you are into making money from domain names, this is your best insurance. You will be able to research and register valuable domains using this tool. For eg. I regged the domain Beatrice Dalle .com (A famous celebrity) using this tool for only $8.95 and sold it for $100. That is a 10 times mark-up. What I like the most about this tool though is that it includes FREE daily domain drop lists. That alone is worth a lot of money (some companies charge $149/month for these lists). You can buy this tool at $249 for a lifetime ownership so there are no monthly / recurring fees + you get daily domain droplists free. It has loads of features including Alexa Rank, Google PageRank, MSN, Yahoo and Google SE links, Overture with/without domain, SE keyword saturation etc. For example, today I just started the tool and downloaded the daily expired list and within 5 minutes I found applebys.net was available. US Ovt score for the term 'applebys' is 4089 and a quick keyword search with SEOToolset tool showed me that the term 'applebys' is searched 514 times/day. Another quick search on Google showed me 40,300 results for the term. And I also saw that all major tld's for this domain were already taken. So I just went ahead and registered the domain at Enom for $8.95 which I am sure I will sell for at least $50 if not $100 All in all a must have tool for the serious domainer and definately worth every penny of the $249. (you can make that back in just 1 week if you are smart enough).
Update: I just found another gem with the help of this tool : CourtneyThornSmith.com (of Ally McBeal fame). US Ovt of 7431 Go ahead and register it
