I have a 4 year old Pixma MP610 with a damaged printhead. And I'm not sure whether I should replace the printhead, or buy a completely new printer. What it all depends on is: how much more difficult is an MG5350 to refill? Easy and cheap refilling is important to me. I know the 610 has great refilling options but I'm afraid newer printers will be more difficult. I would like to pop in a new printhead and keep the 610, but I don't think it'll last long enough. I've been using it a lot for 4 years a lot, and the waste ink sponge is 60% saturated. Chances are some part will break and I'll still need to get a new one. So which way to go? Thanks in advance
