The only modems sold in stores now is the Hitron. Crappy wireless gateway, but in bridge mode it should work just fine as a modem.
You didn't forget the Cisco DPC3825. Like the Hitron, the Wireless gateway is "substandard".
Putting either the HiTron or the Cisco DPC3825 is preferred.
The DPC3825 is not technically sold in store. You can buy one from the rental pool if you want, but it costs more to do that then to buy a retail packaged Hitron.
