Thanks for the advice Horatio.
I ended up buying the Eclipse today and will mail the Kenwood back to Crutchfield. The Eclipse fits great.
I ended up with the $300 price tag (which is $70 less than the retail, but still pricey.) The owner was a nice guy, very "realistic" as you put it. So that facet of the purchase went well.
It's nice not having to worry about my stereo anymore, and the Eclipse is a very nice, well-fitting unit. I do need to wire up my amp sometime, probably next weekend. High-power HU it's not.
