I'm also in the camp of buying used as there are a lot of positives.
Low cost of entry 1st and foremost to see if you truly are going to be bit buy the motorcycle bug.
Most folks dream of riding every day endless miles planning mutiple adventures and so on then reality hits. Motorcycles are way different than cars and on the surface seem like great money savers for commuting but commuting and errand running on motorcycles can be a PIA. Jacket, gloves, helmet on/off every time you stop verses a car get in out and the outside weather condition don't matter. Limited carrying capacity and tires cost more and wear out a good bit faster like 5x faster. A buddy of mine who eats, sleeps and breathes motorcycles and rides between 30,000 and 60,000 miles a year and keep detailed records of gas oil tires has found that a motorcycle is actually more expensive to run than a modest automobile like a Honda Civic or a Toyota Camry. The automobiles get around 7 MPG less fuel economy than the average motorcycle buy the tires are the biggie. 4 tires that last 50,000 to 70,000 mile on a Honda are about $400 per set of 4. On a motorcycle if you rely on a shop you pay about $300 for a set of budget tires that last if you lucky 10,000 miles
Another thing is there are two types of people. Those who have dropped a bike and those who are going too. Dropping a used bike is way less frustrating than dropping a shiny new one.
And finally while the DL may seem like the perfect bike you need to get some miles on it and determine if it "is" the perfect bike. There have been many bikes that I though would be right from me until I sat on them or rode them for a while only to determine my eyes liked what they saw and the rest of me was like now way am I putting up with this bike. My Moto Guzzi Quota was at the top of this list. Looked great, handles great and sounded great. Wind noise and extreme buffeting were conditions that could not be corrected so I rode it 5,000 mile and sold it for what I paid.
At least in the lower 48 there are so many low mileage used bikes from folks than had dreams that never came to become reality I'd truly be hard pressed to buy anything new. New bikes just are not worth the premium over gently used.
