??-John Beck 'Free & Clear'-??

Has anyone seen the late night infomercial of John Beck's 'Free & Clear' system about how to buy real estate free & clear by just paying the back taxes?
If you have seen it, have you purchased it?
Why/why not?
What have you heard about it?
If you have purchased it does it work?
Was it a wise investment?
Are there any other Tax Lien packages similar that you would recomend?

Any help with this topic would be greatly appreciated,
