A Canon Pixma ip3000 or ip4000 would be an excellent choice. There are
no smart chips, the printer actually detects the the physical presence
of ink using optical sensors and their are a wide variety of 3rd party
solutions for the printers.
The ip3000 offers standard 4 cartridge system of tanks with a user
replaceable print head.
The ip4000 offers much the same as the ip3000 but is equipped with two
black inks, one for text printing (using pigment inks) and a high
contrast dye based black for photo prints.
