I've used the trial of RealTime Labor Guide, it is okay for a budget labor guide. On many jobs it actually quotes RealTime, meaning it is quoting what the job actually takes, not what the manufacture supplied labor guide says it should take (of course normally in their favor).
We also have 3 licenses for AllData which is good. We log into AllData a few times a week, most of the information is pretty generic. My techs are all experienced and it usually just takes up time for them to log in and check out procedures. It is invaluable for torque specifications.
If you are doing a lot of electrical repair or need diagrams, I've found that Mitchell has better ones, the OEM and a lot of 3rd party supplied diagrams that go further in depth. I don't have Mitchell, but a neighboring shop does and I have used it for diagrams not available on AllData (or as we call it NoData sometimes).
