Power Hacksaw or bandsaw?

I'm just starting to think I need some means of cutting bar stock other than my arm & hacksaw combo or angle grinder(!)



I'm thinking 4" 1045 steel will be about the biggest dia I would want to cut (I have 1 meter of it in the shed), more likely 3" dia and down.



So far I've thought about a horizontal bandsaw or a power hacksaw, or also possibly making a hacksaw attachment for the lathe.



Forgetting the making something or now, how good are power hacksaws for occasional use? I suspect a bandsaw is far more efficient but that probably only translates to speed and I won't be using it that often. Power hacksaws also seem to be a lot cheaper than a bandsaw.



Any thoughts or ideas?



Thanks
