You should get what you LIKE! It is your kitchen, is there are none others like it, it will help the property sell whenever you may want to sell it. Most home improvements do not ever recoop their cost other than painting.
It you want it, get it. And, by the way, the project sounds really great! You should post a photo of before and after so we can all see.
Also, I did a kitchen remodel once and used sylestone rather than granite. It was a little less cost and less maintenance and still a "stone" top.
