All in one printer for home office

At home, I currently use an HP Laserjet 1020, which has been fine. However, given I'm working from home more often these days I really need a scanner and possibly a fax capability. I don't do anything fancy with the HP, just accounts, payslips, etc. I don't intend printing photos nor do I really need colour (as my children will immediately commandeer the printer and bankrupt me with consumables costs) but text quality is important (hence I assume laser is best). Wireless would be good but not critical.

Can anyone recommend anything? I'm not too concerned about a budget yet as I'd like to see what's out there first. I'm not a complete technological twit but I have to say I find the sheer range of products on offer a bit daunting.
