timmmay: Check out the Epson Stylus range
Cost per page can be found here for some printers. This is USD, and things cost more in NZ due to remoteness, so I figure you're at around $2 per A4 page. That's much better than a lab, even accounting for mistakes and reprinting.
thanks for that link.
I was at Warehouse Stationery today and saw a couple cheap HP printers. ...after seeing that their inks are the most costly, I think I can safely rule them out.
