Let us look at this logically... If microwallet.org is/was offering it as a free service, what would motivate 3 others (who would replace microwallet) to also run it as a free service? There would have to be some skimming/commission for most people to be interested.
My concern as a potential buyer of the scripts was exactly that, how much time/maintenance is involved. I asked that of Land Of Bitcoin and he said he would be putting up an FAQ that would answer my questions. It is not up yet.
I am all about solid automation, the more the better. Personally I wont buy the scripts if it requires too much of my time, even if I can monetize it.
