I'm trying to set up a home network with VOIP. What I want is
evidently a lot like the Billion Bipac 6404 VGP, but with wireless N
instead of G, and I'd also like USB to hook up a flash drive. Looks
like I'll have to split things up to get everything I want.

I'll probably settle for the Linksys WRT160N router, which I've found
for about $35. Can't seem to find a version with USB built in, but I'd
pay an extra $20 for that.

As for the VOIP, I'm comparing these:

Cisco PAP2T-NA ~$53

vs

Cisco SPA2102 ~$55
http://www.amazon.com/Cisco-SPA2102-...ref=pd_sim_e_5

Can anyone recommend which is more flexible? How about easier to set
up and get working?

Thanks!
