At first, used 2 Cisco 3750 doing etherchannel. They can L2-loadbalance using L3 parameters (src-dst-ip pair) which worked fine until MPLS was deployed, with a side effect of breaking the loadbalancing effect. It started working again when replaced with Cisco ME6524, which can L2-balance with L4 information and MPLS labels to a smooth session-based balancing with up to 8 links. Even without the MPLS license, which is the expensive part, my guess is that ME6524 can L2-balance with L4 information and could be an option to such a job. And after seeing Mikrotik RB450G load-balancing 200 Mbps with session persistance without issues, I would consider an RB-1000 to load-balance 2 links...
