so whats wrong with the stingers? i have had the old yellow one since 2002 and its worked great, no issues, however its loud and kinda of slow and is not rated for 410a so ill need a new one. I see stinger has anew one rated for 410 and a lot more , however i kinda of breezed thorught someof these posts and see there are issues with some units needing the tank cooled or the reset limit popping all the time.I want to know which units need all this just to revover refigerant as thats IMO is ahuge time water and a hassle. I want a nice unit that is reliable and works great out of the box withoiut a lot oif these side issues.
I notices some units have no guageas at all and have aseperate maybe optional manifold that you buy and keep seperate from the pump housing, which unit is this and why do they do this?
again my old stinger works great after all these years but is going to be my designated r22 pump so i am in need of a 410a revovery machine so which should i buy and why?
