Whatever you do, do not get a used unit, the market is flooded with these. I know you have not mentioned anything about getting used but just wanted to warn you in advance.
I have got HP Laserjet MFP M127Fn (Printer, Scanner, Copier, Fax), no Wifi but has Ethernet port which can be connected to the router and used by any device connected to the router. I think it was around 17-18k, now it goes around 21k... I am happy with it other than the fact that the LCD info screen does not have any back-lighting... and the genuine toner cartridge will cost you about 5-6k. I was used to Chinese toner replacements in genuine packaging, costs around 1800-2000 PKR but got two very crappy quality ones and had to change the roller in it for it to print in good quality.
If I could make the choice all over again. I would either go with Brother or Canon/Epson perhaps. Not sure about this latter one but I read on some Pak news site that the brand is introducing MFP/Printers etc. in Pakistani market and one of the things it offered was MANUAL refill system officially supported by the toner cartridge. I would definitely look into that.
Inkjet MFP might cost you less with Wifi included but not sure about the ink thing. In past, if you did not use the ink, it used to dry up plus again, the cost of genuine replacement would be high and unsure about knockoff inks.
