I need to buy a new printer to replace my Canon Pixma iP4000. Things I'm looking for are: separate color ink cartridges and paper feed from the top (this is crucial--I bought an iP4820 and it's going back because it will only feed regular paper from the bottom and photo paper from the top). I print an occasional photo, but do not feel that I must have a photo printer anymore. I'm looking in the $150 or less price range. I would prefer a Canon because it's what I'm used to, but am open to suggestions. Any suggestions? Thanks!
