Self Adhesive Tiles?

[Eric Barnett]

Looking to do a quick job and change floors in a multi, thought about pulling up old linoleum in bathroom and kitchen and wanted to put tiles down but looking for something relatively easy and cost effective.  Any bad or good experiences with this type of tile or re-flooring process?  Has anyone ever put these down over an existing floor such as prior tiles that are scratched or stained from past use.
