Need some suggestion about load balancer

We are setting up two connections from different ISP's through a load balancer. We use Juniper Netscreens here so I was looking for Juniper brand load balancer, unfortunately I found out that they just got discontinued recently, there is no point buying them.

I would like to get some recommendations to load balancer devices that are inexpensive, easy to manage, stable, and with QoS feature, we only have ~30 users under this network if the that is a concern.
