"professional grade" dual-WAN routers such as LinkSys and TP-Link also simply offer fail-over.
PepLink offers the only low-cost dual-WAN port true load-balancing router ($295) with a graphical user interface that anyone with a bit of networking savvy can quickly configure. And PepLink offers models with 3. 5. 7 and 13 WAN ports with true load-balancing. Another low-cost option is MikroTik, but of course you need to be more technically savvy and with knowledge of the MikrTik RouterOS to configure them.Author: George Hardesty
