Advanced Email Collector. Find emails as fast as your bandwidth will allow, supporting up to 99 simultaneous connections. Elite Prosperity has the ability to scan for an unlimited period of time, with no url level limits. This is a feature not found in many other collectors.

Also includes a list manager, which allows you to kill duplicate emails, merge mail lists, filter out unwanted words and much more, all in a great interface.

Normally you would expect to pay at least $80 for a similar product.
