[SDBUG] Cheap FX/FXO cards to test asterisk on Freebsd 6.2?

[Pedro Moreno]

   Hi people.

    I have another project, i want to test asterisk, i already setup the 
server 1.4.4 over FreeBSD 6.2-p5.

    But to really test asterisk i think i need some hardware, FXS/FX0, i 
have one phone line ready to test and start learning asterisk, i want to 
change my old PBX-System running Altigen.

    Does someone knows one cheap card for freebsd guys?

   Thanks all for your time!!!
