Which PCI BRI card for asterisk?


i Have a question. I plan to build a fax server with asterisk, hylafax and iax modem. It will handla 3 or more ISDN line.
I tried to find a BRI card for this, but I can’t decide which better for me. I think I have 2 alternatives:
1: Sangoma A500 2-24 Port Scalable S/T BRI
2: Digium Wildcard B410P
My question is which is easier to install in linux, specially debian? What are experiences with these 2 cards?
