Great Review. I especially like the premise behind how you intend to go forward with reviewing premium themes. There are quite a few out there that may prove interesting to see and read a bit more about before considering purchasing.

The points you bring up about Eventina having compatibility issues due to jQuery conflicts, at this time, would stop me from buying it; and given that the theme is the newer item I would think it would fall to the theme developer to look at "fixing" the issue if the plugin is still current and well-used.

I myself like using Comment Luv on my blogs, too; and, would be at odds if it did not work in a specific theme I had paid to use.

All in all, from what I have read here this is a good looking theme with a great concept in the back-end options set up. I could imagine at least a few different blog concept ideas that it would fit well.
