AirlineApps is certainly worth the money. I got my first response three days from starting my profile- it wasn't even complete when Comair contacted me for more info. I had just entered my name, hours, ratings, education and 2 references when they said they were interested and I should complete my profile. A week after I completed my profile and targeted another company they called.
As stated above, it's a super back-up to your logbook.
