it depends on what you are doing with the network i guess
my personal experiences with home wi-fi networks are just plain bad.
i found that internal and external usb dongles tended to get incredibly hot when gaming or streaming large data for long periods and would cause disconnection issues.
i found that i had marginally high ping in games compared to a wired connection, even using recommenced and expensive hardware.
i used to get constant disconnections, from either phone signals, microwaves, neighbours wifis, who knows.
in the end i just wired my entire house neatly and put gigabit Ethernet ports into every room.
that is my personal experience and after all the problems it used to cause me i would never go back to wifi.
as i said though it totally depends on what you have in mind for your network.
as for recommendations, the parts i found that worked best were
usb wifi adapter netgear wn121t.
routers sitecom wl-308 and the netgear dg834pn worked well.
