im not sure its worth it anymore to try. the big boys, pool.com, snapnames, and enom have so much more resources to catch expired domains
This is depend on the system of the registrar. For me the best site to use is GD coz the fee is cheaper and i always can get the domain i back order without failed.
It depends where the domain is registered. Every drop dealer has agreement with some registrants. Check where the domain is registered and then who's the related drop dealer
If the domain is not registered at godaddy, godaddy won't get it 99% of the time. Pool.com has been catching more stuff then snapnames.com for me. I think namejet.com does it too. You have a better chance of handregging a domain you want on the day it drops them godaddy getting it.
There are no tools out there to beat the pros at snapnames and namejet... just wasting your time. If they want the domain they will get it before you. However you can get the lists from them if you wish to do research.
