I looked at that Billion router. It's comparable to the Netgear, except the Neatgear has simultaneous dual-band WiFi while the Billion is only 2.4GHz. That's not a deal-breaker, but it's a distinction.

What's sad is that many vendors designed and built these things with previous-generation WiFi (e.g., this D-Link) but haven't updated them. Maybe this class of product just doesn't sell much.
