The only one I've implemented before is liveZilla. It worked great in my limited experience with it, I've had no complaints from the client, plus it's FREE!!
I guess you need a chat for support and indeed liveZilla and liveperson are the best. But you can also use a social chat services that allows your visitors to talk to each other. You can choose from 123chatflash, rumbletalk or xat
I recommend you to use Live2Support's live chat software on your website. Its secured, multi featured, fast and affordable. 24/7 technical support. For more information visit website and chat live with customer care.
I have one web development company my website is http://www.esparkinfo.com, I want to provide live chat facility on my website.
I have got suggestions from my friends about livezilla to provide online chat on website.
Please suggest me best live chat applications I can add on my website
Thanks In Advances
