Went the 36 volt unit as I want to get the mower too at some stage.  I just wanted to be able to cut up a few small branches to make a small fire with when camping, but it is much more capable than that.  I used it around the FIL's farm and cut up 10 hardwood fence posts into fire wood and the battery still had 3/4 charge left in it.  It is the same size as a small petrol powered saw and weighs about the same too, but it also cuts better than the cheap ones which really surprised me.
Not as cheap as a petrol powered saw but suits me for what I want down to the ground.  If you were heading out bush for weeks on end it isn't what your after but for a weekend saw you can keep in the back of the car and not have to worry about the smell of petrol, etc - they are great.
