Canon or Brother.
Although Canons become more expensive to run with every model they release. They are very good machines though.
Brother seem to be decent quality, cheap to run and reasonable to buy these days.
Take a look at the MP640, bit over budget but it looks like a good machine or for slightly cheaper the MP560.
For Brother take a look at the DCP585cw, think you can pick them up for around £80.
I have 3 Canon printers in my house. MP610, IP4200, IP3000. They have been reliable and good quality but Canon have really started pushing the cost to run up. You get about half as much ink as two years ago for the same price, which is a big disappointment.
