I have a Brother DCP-T720DW, a 3 in 1 (print,copy,scan) that can connect wireless.
It is not in the current line-up for Brother anymore (I've had mine for 3 years or so), but it's still available at some dealers, like here .
I bought mine at DG Tech on Perdices Street, they may still have some also.
Obviously it does depend a bit on your needs what your best choice would be, if you don't need colour, and don't need copy/scan functionality, then you should be able to find a cheaper option. Epson and HP are reliable brands also. I would definitely go for a laser printer though, the inkjet stuff is a nono. (cheap to buy but crazy expensive to refill).
