I'm in Lakewood, bought my 2008 650 last January from a guy in Moab, UT. I've been riding dirt bikes for 15 years and this was my first street bike. I love it, but wish it had some more power for going over the 10,000+ foot 65mph passes we have up here.
I think a DL650 is a great first street bike, probably because it was my first street bike. Seat height isn't cruiser low, but it's easy to get one foot flat on the floor and the other foot toes on the ground. I'm 5'09". Definitely go used. No need in dropping a brand new bike. I somewhat agree that a single cylinder DRZ400 or KLR would be a better beginner bike. Definitely easier to pick back up and less expensive plastic to get mangled. We aren't trying to scare you about dropping bikes, but I ride dirt bikes professionally and have dropped my Wee 3 times, all under 3 mph.
What are you looking to spend? Craigslist is where I look. There's Motorado, a purely consignment dealer, on 6th Ave. Ron, the owner is knowledgeable and not pushy. I was in there last week looking at a Multistrada.
There's a KLR and DRZ there right now for you to go sit on.
Not to second guess your settling on a VStrom, but what kind of riding are you interested in? Commuting to work, touring, dirt roads, to the local bar and back, or what?
If you're looking for the 'adventure' bike, find one that someone has already outfitted with crash bars, skid plate, side cases, adjustable windshield, aftermarket seat, etc. I paid $4100 for my 2008 with 35k miles on it. I added up all the accessories it was coming with and got to $3500.
