Well, after reading all that:

All these solutions need a certain time to set them up. I cannot really 
tell about their quality, but you should consider, that a solution like 
CARP can detect and do a failover a problem, when a server crashes - but 
not a service failure, like httpd not working correctly anymore. Then 
it's a question, what you are trying to balance. http only? If so: How 
about session handling (if you need that)?

We use a hardware solution based on Alteon 180 (or 180e). You can buy 
those for less than 2000$ and they save you a lot of headaches.
