I'm looking to refinish basement floors that formerly had tile. Once I get the residue up and a clean concrete surface, what are the best choices for an etching & staining product? Local concrete place has a one-bucket etcher/stainer (but no sealer) for $80/gallon. Direct Colors Inc online has a complete kit, etcher, stainer, sealer and all the accessories for about $200 for a 200SF kit. Other recommendations?

I want metallic epoxy in my basement.

That looks cool. Anything else out there?

For etching use muriatic acid in the pool idle at the box store...
