AMD Power reviews the Dual WAN router by Xincom which offers both outbound and inbound load balancing.
Quote from the review:
“The DPG-602 offers the same outbound load balancing features as the 402 along with an inbound load balancing function. Inbound load balancing can be very advantageous for small to medium sized businesses. For instance, a company can save a great deal of money by switching from a T1 connection to two cable internet connections. Normally, the upload speed is much slower for a cable modem than a T1. However, with two broadband connections at 4000K downstream and 500K upstream a piece, you can get near T1 speeds on the upload and up to six times faster download speeds. “
