router/firewall, wireless gateway recommendation for home user

["sun sadm" <sunsadm () gmail com>]

Hi colleague,

1) We have four computers (Win XP, Win Vista, Linux, OpenSolaris)
connected directly to the Internet. I wish to setup a firewall and NAT
device to reduce direct attacks (additional security layer). It should
cost around $100 and very qualitative, user friendly,  customizable
from a security standpoint.

Which home product do you recommend and why?

2) We have an Ethernet cable setup. I don't wish to use a wireless LAN
for the four computers (different reasons). Only for my new
PlayStation Portable, we are forced to buy a wireless access
point/gateway. Here again my criteria are: standard compliance,
security, user friendly, customizable and price around $100.

Which home product do you recommend and why?

thank you for discussing and hints
Nico
