Chainsaws can be lethal if used incorrectly. You might consider having some profesional tuition not only for using but also for maintaining properly - especially as regards protective clothing. Beware of chainsaw 'kickback' http://forestry.about.com/od/chainsaws/f/cs_kick.htm
I did consider getting a chainsaw but settled for an axe and a splitting wedge. Latter can be used with a heavy hammer 'one handed' - but is only useful for splitting along the grain.
Good luck
