anyone know about United Tax Liens company?

[Ed Williams]

I got an investment come-on from United Tax Liens for investing in tax liens.  Does anyone have any info on them, good or bad?  They sell a service to help newbies get started in tax lien investing, as well as other services downstream from there.  May be the old sounds too good to be true.

Related, if I do want to get started in tax lien investing any suggestions on the best way to start and sources of education?

Thanks!
