I also find the ones that use two wrenches much easier than the ones with some kind of locking mechanism. One place I worked had a Makita, probably a 3612, that had a locking pin and it had gotten worn and didn't hold very well. No idea how hard it is to replace one if it happens so make sure you have it pushed in well before you try to unscrew the collet nut.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
