Blogging Comments Systems. Suggestions???

Hello, dear readers! I am opening the floor to suggestions on new blogging comment systems. I want to be able to comment back to you but want a good system in place to do so. If you are like me, you don't want to subscribe to ALL comments and fill up your inbox with comments you may or may not want to read. I have looked into Disqus and IntenseDebate but have also heard some bloggers/readers have had bad luck with these systems. Do you have any suggestions for me? I feel commenting back to all of your sweet comments is very important. But I want to implement a good system that works for all of us. THANKS in advance for your suggestions!
