I installed one of those fans a couple of weeks ago. It bolted up nicely, and it looks good. My only gripe is that the foam strips they give you to install between the radiator and the top and bottom edges of the fan shroud don't look so great.
I went with the version that doesn't come with the controls. The female half of the electrical connectors were not included, but fortunately they are the same style of connector that is used in the OE under-dash harness for the dome light connection, and I had a couple extras of those. I have my Holley Sniper controlling the two fans.
I have yet to see if these fans will keep up in the heat of Summer.
