Yeah definitely not cheap. But lightweight, strong and they look awesome as a bonus.
And a funny anecdote, as an experiment I didn't tell my fiancée I was changing wheels so I could see how long it takes her to notice. Not a small change, 19" silver wheels to 18" dark gunmetal wheels. They were changed on Thursday and she's walked past my car in the carport at least a dozen times and I even picked her up from the city in it so she saw me drive up to her. Still hasn't noticed.
