There are several tools for domainers. One of my current favorites is the "recently deleted" tool from Name.com. The tool allows you to enter a search string and adjust some other inputs such as allowing names with hyphens , string position in the domain name, and domain length. You can also decide how far back in the deleted queue you want to search, from hours to days.
Lets say that you favor real estate names. You could search on the string "real estate" telling the tool you only want names ending in ".com" and that the string should be at the end of the domain name (ie. xxxRealEstate.com). Also enter how far back you want to look in the "Deleted within" field, and you're set. Sure, someone could snatch the good names on the drop, but I assure you that some gems make it through. It's up to you to sift through them and grab them. This tool makes it a whole lot easier.
