I've read quite a bit in this forum, and the general consensus seems to be with the IP4500 or the equivalent AIO MP610. I was looking at the MP620 because of it's networking capabilities, and I don't know whether to get it or not because the website states taht the MP620 uses the same kind of refills the MP610 uses. But the some posts in this forum suggests otherwise. How do I know for sure that even this MP610 uses the CLI-8, PGI-5 ink? I'm thinking maybe it's a specific model number?
