OK experts...
I'm shopping for a new ride. I fell in love with the ride of the Trek 8.5DS...and the color scheme isn't bad either.

What is the difference between the DS models...I know it's components!
But what kind of components should I be looking for?
Should I spend the $$$ on the 8.5 or but something a little bit cheaper?

Any, and ALL help is appreciated!!!
