Panama Rick is correct. In fact there are now...
double deckers for $3.00 table minimum in some areas of Las Vegas. Get a copy of March CBJN , it's pretty cheap, about $13 or thereabouts.
You can sit there, flat bet $3 while counting for your playing decisions and insurance decisions, and (if you want to party) get blitzed on free drinks, with very little cost per hour!
Just don't play any serious games when blitzed!
