I'm not advocating either approach, but when this subject comes up on the forum most people recommend replacing with a modern cartridge type bracket. They're fairly cheap, work well, last a long time and don't require adjustment.
The opposing argument is that cartridge BBs are a reflection of our disposable society. The counter-argument is that, since cartridges last longer than the normal interval between cup and cone BBs the cleaning, bearing replacement and regreasing required with the conventional BB is more wasteful.
Both will work and neither approach is all that complicated or difficult. Pick whatever makes you happy.
