Wow! i am surprised it is discontinued,i only bought mine a few months ago,i think it was there most popular monopod.And no you can't switch out heads on the 560.I would look for a 561BHDV-1 on ebay or amazon as the head is better. EDIT: It looks like they discontinued the 701 hdv head also....what a bummer,i'll have to double check my 560 to see if you can or can not switch heads,it may be possible after all.
