There wasn't an update on this and I wonder if OP is still looking.....HEY OP! YOU STILL WANNA BUY THE BEST BIKE EVERY!? haha
well my 2 cents is to check Craigslist at least once a week and either write down the info or keep an eye on stuff, sometimes a bike will be listed on there from a month ago, then they will either bump it up or re post to help it get seen.
In 5 minutes of searching I found 3 Stroms in his area, 2 650s and 1 1000, all in his 4000 ish range.
2007 SUZUKI V-STROM DL1000
This one is pretty cheap, can't tell if thats 109,XXX MILES or Kilometers, but you could def offer less if you got cash.
2009 Suzuki DL650 V-Strom
Ads may say the price is firm, but if it hasn't moved in a week and they get desperate they might take a few hundred off.
Higher mileage found in the "nearby search" under the local listings. Its got farkles and new sprockets and a rear tire. It has also been posted a few times recently and once a month ago. The owner could be willing to take something low as $3500, again if you had cash.
CASH is power on a site like Craigslist. Not a lot of people are trust worthy these days so not a lot of people are willing to take payments or personal checks. Some might be willing to go with you to your bank, if they have time. Keep searching and you will eventually find damn near exactly what you are looking for.
