Ouch. That's a lot of splurge on a bike for me. However, you bring an interesting thought, if you spend it you'll be more inclined to get the usage out of it.
I wear Oakleys. I used to wear cheap crappy sunglasses and didn't care about them. They'd be scratched up in days, lost, sat on, etc.
At $20 a pop it wasn't a big deal. I spent $140 on a nice set of Oakleys and they lasted almost a decade!
Sometimes the value proposition is that you'll feel obligated to do more with or take better care of something you spent more on.
