Are you looking for a deal or just a Big Dog? There's a $10K difference in those two bikes. For $25K, you can get just about anything out there, especially if it's used.
Have you ridden either one of those models? I think before I spent that much money, go to a BD dealership and test ride. You may find that you like the Ridgeback, Chopper, K9, Pitbull or one of the others even more. If you have $25K to spend, pretty much any model is available. A struggling dealership may sell you a lingering '08 or '09 model for that.
