if i was to buy a machine to do the job, which im sure i will, probably when im 42... i would buy the electric one, cos if im buying a machine to do the job, then id want it to do the job. the manual one, not that ive ever used one, sounds like a lot of fiddling about, levers, knobs and whatnot, if you want to save time, and effort, then get the machine that does what you need, ie spilt tonnes of wood with as least hassle possible. good luck!
