None of them. the Cartriges are too dear.
What about a Canon IP1500.
It uses BCI-24 Black and BCI-24 Colour cartriges the same as my Canon MP-260.
I picked up a black/colour twin pack for 1.99+ Vat from Cartex.co.uk last week (if you buy 5 packs at a time, listed under Canon S200). £12 for 10 carts isn't bad at all and I've never had a problem with them. Black carts are 99p + vat for 5 or more with free 2nd class postage.
True I wouldn't print important pictures with 3rd party carts (the colours are a little muted) but for day to day use why pay £15 for 1 black Epson cart.
You have always got to consider the running costs with inkjets and the costs are very high for cheap inkjets.
