Hello Professional Recruiters on RecruitingBlogs.com!

I've been thinking recently about which ATS is better to use. There are so many of them on the Internet!It's hard to choose the one that will match our needs..

I am seeking for an ATS that:
1. Will allow us to keep our data in our server only
2. Will scan our disk looking for resumes in txt format, and import them into the ATS
3. Will be simple and intuitive to use
4. Will have a real person, tech support, free, based in USA
5. The one with a trial version

DO such ATSs exist?

Thanks everyone for participating! :)
