I've been looking at both the Asus RT-AC66U and the Draytek Vigor 2130n that have had good reviews from Geekzone users, but budgets are tight so what cheaper alternative would recommend? Wifi isn't required as the small business already has a separate wifi network, and features such as USB ports aren't required either.

One confounding variable is that web filtering services will most probably be required. That may occur on the device, or perhaps via a third-party could-based service.

Any suggestions most appreciated.
