I'd say neither! Threw away each of those at the end of last summer, both needed parts. Parts were damn near the same price as a new JB"I've got my Gas Mechanics license"

Choosing between Robinair and and Mastercool is kind of like choosing between a 1988 Yugo and a 1988 Dodge Colt....
(Note to self: Research newer crappy car equivalencies.)If more government is the answer, then it's a really stupid question.

i walked into the supplier the other day and at my supply house they have started the sales on seasonal stuff already. im thinking of picking up myself a bullet vac pump and a micron gauge vac pump goes for approx $ 299 and the micron is approx $150-200 cdn. you should really go walk into the supply houses things are always on sale at the beginning of the season. i remember getting my analog gauge(YJ) and 5 ' hoses w ball valves for approx 120 and i got a shrader core remover kit with isolating ball valve for like 40 bucks. i kinda happy that morning but broke at the same time.
The supply house that i use is called Eastern Refrigeration supplies. aka MastersGet er Done!

Have tested both Robinair or Mastercool 90065 and they both work well. Tested a single stage 6 CFM and a two stage 1.5 CFM the 1.5 got to 500 microns first and went to 25 microns the 6 CFM took 4 time longer to get to 6000 microns.

The test show that two stage pump will outperform a larger single stage pump.
