If the autodoc becomes available for purchase, how about having to recharge it with super stims and MFC from time to time? To me it sounds logical that it needs power (MFC) to operate and has a limited supply of healing chems. Or perhaps it should only be availabe for bases. I mean, a lone autodoc sitting in a tent in the middle of the wasteland sounds a little odd. Or maybe a single player should be allowed to buy an autodoc if he/she has built a house. In another thread someone suggested that players could build a shack or even a house and having an autodoc inside a house doesn't sound that ridiculous. And of course there will have to be some requirements, maybe sufficient IN / CH + doctor / barter / speech skill check to be able to convince a doctor to sell an extra autodoc for a hefty price. Or maybe it could become available for purchase after completing a quest.
