MCC. Nothing comparable around. Use them now a couple of years, printed of some pages, works perfectly. No need for other, much much much more expensive "solutions".
EDIT: If you pay a "one off" fee in MCC(which is the current deal), how could they charge you later on monthly? You made a deal with this company, if they decide to "move on" and change model you always can sue them.
Afaik MCC is thinking about a monthly fee for NEW JOINERS in the future. Just another reason to get it now.
