I use LVS for more than 3 years now, distributing requests to 60 web
servers for airline companies B2C and B2B systems.
One of my directors is up for 795 days, load avareged 0%, handling 300
connections per real server and 40 Mbps os traffic constantly.

You cannot go wrong using lvs and keepalived for failover protection.
It is definitely one of the best piece of software I ever used.

Paying for a load balancer just because it "seems like" it would be better is a fallacy. Everything has it's positives and negatives. LVS (via keepalived) is a huge part of the infrastructure I work on daily, and it's always been reliable.
