Assuming that you already have a Linux PC permanently running the simplest
way to create an Wireless AP is to buy a Prism based card and then run
hostapd on the machine.  This is what I'm doing.

The hostap kernel driver has been driving my card for ages now (machines
been up for 77 days) and you don't need much power (my AP system is an
old Pentium 100MHz).  The hostapd provides the extra stuff need to turn
the Prism WiFi card into a base station.

Description: IEEE 802.11 AP and IEEE 802.1X Authenticator for Host AP driver
 hostapd is an optional user space component for Host AP driver. It
 adds more features to the basic IEEE 802.11 management included in the
 kernel driver: using external RADIUS authentication server for MAC
 address based access control, IEEE 802.1X Authenticator and dynamic
 WEP keying, RADIUS accounting.
