You need to marry your budget with what you want. I sold my bike a couple of years ago but I've generally ridden Road Kings. They are my compromise between a big bagger and a smaller bike.
For me you have a touring bike without the counter-rotation so the bike shakes and a rigid frame and the softail which has a smoother engine and a cantilever swingarm with hidden shocks. The Fatboy and Deluxe are my favorite Softails. Road Kings are touring bikes and I like the shake. I like the CVOs but they are EXPENSIVE.
Once you have your budget and your bike (go to the Harley store and ride one of each class) then you can get a range of years to look for. You can find a deal this time of year on a bike with low mileage and no history of repair or accidents. If you really take your time you can find the right one with updated pipes and more to get the sound you want.
I like to find police bikes used in funerals and/or parades (generally Road Kings) that have been modded back to a regular bike. You can get a year or two old bike with the big motor cheaper than most used bikes. But you can find civilian bikes that are just as nice and don't have any remnant police look or equipment for the same price if you take your time.
Did you know there are only 5000 Snow Leopards in the wild now and they are confined to Central Asia? However, the effective global population (those likely to reproduce) is less than half that number.
