watch slickdeals and fatwallet, they'll have deals come through every so often on laser MFC devices
but some questions:
is networking important? wireless networking?
is fax important? being able to send AND receive from a computer?
does it need to be mac compatible?
some of the older ones don't have vista/7 drivers or certain features don't work under vista/7, so check the amazon reviews carefully
At that price point many brands and models of lasers would fit your spec's. But you should also include how big your expected yearly printing volume is expected to be, it cost a little extra to get high volume toner cartridge capacity that will become recommended if your yearly printing volume is high.
i'm partial to the brother line, and Amazon has MFC-7340 for $140 shipped, but the Canon should be a fine choice
however the Canon cannot receive faxes to the PC while the Brother can
(the Canon can receive faxes, but it has to print them out directly and then if you want them on the PC you have to scan it back in)
