some new Epson's aren't that cheap to run at about 20 quid a set of ink
so best advice would be check the ink price before purchase.
brother and canon are also cheap for ink @craigneuk will be best to ask on running costs
Brother £1 a cartridge Epson From £1 canon pixma mg5450 £1 a cartridge
if you pm me what you are going to buy i will tell you how much cartridges are @liamlind1
