I have a 1995 e300d with 230k on it. I was quoted $72 from Phil for a remanufactured Bosch injector. I can also get these rebuilt and also tested to be within 30lbs of each other for $60 from Bosch however I will be without use of my car for about a week.

Should I wait and save $75 and get a tested unit or are the ones ordered online always within spec? To be honest I have heard bad things about the remanufactured injectors ordered online. Thanks
