I've got a Makita N1900b, and I like it. It is good at taking off the dirty surface layer before putting a nicer tool to your wood, and to take out really uneven warps, bulges etc. Even at the finest cut, it is hard to get a really nice surface because I find that one side of the blade or the other ends up a bit deeper than the other. It works well for doors, and chamfering trim too.
You really have to be carefull with them, however. Mine ate it's own power cord in a rather dramatic display, and just a reminder... sparks and plane shavings are not a really good combination.
I've got carbide blades in mine so they do alright, but when they dull, you will notice as it takes more force to use the tool.
The Makita is really designed for right handed folks, as the chip discharge is on the right of the tool, but some mfrs make units that discharge either way.
Chip out depends mostly on the grain. With really new cutters, it isn't bad, but some use, and some wild grain or spalted wood will result in some tear out.
I like mine, but sometimes I prefer a scrub plane, just for the appeal of wood workinginstead of power tool using.
