Have you got a biscuit jointer at work, or do you use the plane or sandpaper technique?

Sam, I think you may be confusing a JOINTER, the machine I referred to, with a BISCUIT JOINER (note it's biscuit joiner, not biscuit jointer -- I don't mean to get all nitpicky on you, just seeking to clarify terms and meanings). A JOINTER is a large machine much like a giant upside-down handplane, with a spinning knife head in place of the plane blade. It's called a jointer because it creates flat, straight surfaces for glue joints. If it's well tuned up and its knives kept sharp, and if you use a slow but steady feed rate, it can create glass-smooth, perfect edges/surfaces. A wonderful machine -- I use mine all the time.
A biscuit joiner is a different animal entirely: a handheld power tool that's used for a specific, modern type of joinery I've never heard of anyone using for any part of guitar building -- though I suppose it could be used in a neck joint... Fabio Ragghianti makes a neck joint that's similar to biscuit joint.
