I bought mine because of all the 'ticking' rumors going around. I got it D & H for $340 about a year ago, right before my 12 month warranty ran out. Did I waste my money? Maybe, 32K miles and no ticks! Figures!

I got mine from D & H as well, for about the same price, soon after buying the bike. The ticking started around 12,000 miles, and got pretty bad by around 32,000 miles. The ~$2200 repair bill was covered. At ~42,000 miles my ignition switch died; I don't remember exactly how much it would've cost me, but at the very least it was as much as the YES.
My advice: if you intend to put lots of miles on the bike, and/or to help maintain its resale value, YES is a good investment.
