That could be a tough choice, I had an 07 DL1000, a ton of fun and plenty of power, till it was totaled by a pickup truck... Suzuki had just announced the remake on the DL650, so I healed up, and replaced it with the "new" Wee. I absolutely cannot say enough good stuff about the 2012 + DL650. My wife had an 08 Wee, and as nice as it was, the newer model is very nice, enough change on the motor to be noticeable, nicer dash, with gear indicator, thermometer, trip computer, etc, all around, a very nice bike. I use mine for commuting and multi state tours, and it's very comfortable and capable of that, even two up.
You may have seen this article, but it seems a good comparison of the two. Last summer, I rode down Hwy 1 to Malibu and zig zagged back north through Nevada and California, those roads and bridges in the article look very familiar. Good luck with your choice, you can hardly go wrong.
