You need to state where you are at, as models vary by region.

For a basic printer: Canon IP4300. IF you want multifunction, the Canon MP600 has the same print engine. In the USA, both of these need minor modification to print on discs.
These models use individual ink tanks, so you only replace the inks that you actually use up. The separate tanks cost around $14, how long they last is entirely dependent on what you are printing.
