Seeking Comment display plugin

I’m currently using the Ajax comment display plugin & while it has some very nice features I find the threaded display to be graphically confusing. I was wondering if anyone uses a diff. plugin that they like in which it’s not as confusing to follow comment threads in which people are replying to each other.

I could always revert to the default comment display though I liked the idea of threading the discussion so people can better follow who’s replying to whom, etc.
