Question about Load Balancer

I need advice for my company. I've been looking through a couple of sites online about server load balancers. My company currently has 2 servers and we're skeptical about server overloading, since we've heard stories about other companies who have had that problem. I've done my research and have found this company who specializes in load balancers for small and medium sized businesses called Kemp Technologies I've checked out competitors such as Barracuda and F5 and I've seen comparisons in price and quality, so I'm curious if anyone has checked this site out and could give me some more information on it. Thanks

Hard to give a recommendation without knowing the bandwidth you are currently using and which level of traffic you currently reach (respectively your expansion plans for the future).

If you are relatively low on traffic (and said this, most online businesses do not need a load balancer overall), there are tricks with DNS configuration you can use to split traffic to different servers... or simply use one single stronger server together with a low-powered backup system that mirrors the sites content (just for ensuring to be still online if your single main server crashes).
