The best time to buy ARC is right when a "new/improved" model is replacing the now hardly-worth-listening-to obsolete model, which is every other year or so. Right now you should be able to pick up an LS17 or 27 or whatever (I’ve lost track) for a couple thousand off list. Check the outside of the sealed carton for the stamp "Factory Reconditioned", a method ARC has used to get rid of pieces returned for repair but never paid for.
