that price seems about right, going rate is STEEP.
it would look strange, no doubt about it. when i had my jeep in for service once, they put a set of stock 26's on it, and then took a picture of it for me. i've got a 4.5" +1"BL on it, and it looked obnoxious as hell.
i think for a DD, either go down a size to 33's, or just keep it the way it is. otherwise your COG will be quite a bit higher and quite a bit more hairy to drive on the road.
