"Expireddomains.net" and "Nameinvestors.com" are two great tools to find the drop domain list. You can use various filter options to find the names you wanted to register. You will also find the "pending delete" option from where you can get the names to backorder.
These sites update expired lists on daily basis and for some extensions more than once a day.
Hope these tools will help you to find some gems to register.
When you log in to expireddomains.net, you will find "Deleted Domains" in the left-top corner. Those all are expired lists. There you will see extension-wise domain lists and a "Pending Delete" list. Choose what you need and then go for filter as for example, word count, characters/numbers, time of listing, number of registered domains, etc. Hope this will help you.
Thank you @amplify. That was insightful. Drop on the East Coast is 2pm. You can also plan ahead and see domains that are dropping 2,3 days ahead of time. I recommend making a spreadsheet to organize your priorities.
