I already own a Canon Pixma ip 2000 and wish to buy another printer in the near future as we are buying a second PC. I really want a fairly basic/cheapish one,but the main criteria is one that has easy to fill catridges as the children get through quite a lot of ink doing homework, pictures, etc. I was going to go for a 3000 or 4000 but have just realised that these have been discontinued and replaced by models with chipped catridges. Can anyone suggest which printer I could get that will be easy to refill. Thanks.
