I also like the Lyman because it gives an indication where pressures will be with the loads provided.
The thing is, it depends on how many cartridges you intend to reload. Yes, the Lyman manual is very good and covers most cartridges out there. My only issue with it is that they don't list enough different powders. That's where other manuals come into play. One other thing, some of the information in the older manuals conflicts with the information in later manuals. Some of the earlier Hornady manuals and even Lyman manuals will give loads that are now considered to be to hot. Mostly because of liability litigation from various cases.
Gun shows are great places to pick up used manuals. I have at least twenty. Most were picked up for a couple of bucks at yard sales etc.
If you are shooting a strong modern firearm, with late manufactured components, then the Lyman 49th would be your best bet. If you are sticking with a certain brand of components, such as Hornady or Sierra or Speer then go with their manuals as they find the best components to match their products. If you are a Hodgdon powder fan then use Hodgdon manuals.
Lee prints a good manual. Loads listed are on the moderate side in almost every case. If you are extremely cautious and a one firearm person then it is a great manual. Sadly they stick with the older powders and don't have much information on the new releases.
