Got a simple scenario with two web servers for redundancy and to scale.

But how do I make a two web-server setup fully redundant? I can think of two solutions;

two web servers, one load balancer spreading the load. one extra machine for the load balancer. but how will the load balancer be redundant?
two machines, each running the web server AND running a load balancer, spreading the load over. have a DNS entry point to both of the machines. no extra machines needed for load balancing.

How do you guys normally solve this kind of problem?
