   Including mop the floor after? That's faster than I can do it on a pair   
   of knees that work just fine.

   California stopped the sale of R12 in the state years ago...those in the   
   know around San Diego merely went down to Tijuana and bought it. R134 is   
   going to go the same route in the near future and it will be made   
   available too. The newer, replacement coolant will not be backwards   
   compatible either.

   And more complicated to operate...I had a hard time getting the most   
   recent one working the way it should and they lost the manuals for those   
   older machines.
