Being the owner of an XChallenge, I'm a bit biased. But I wouldn't dismiss the XCountry. I think you'll find the vast majority of electrical issues to be related to the battery recall(s). If you do get one, make sure it has a Yuasa battery, not the Exide. The first recall just replaced the Exide with another Exide. (Exide is generally not a bad battery brand, but this particular model had issues).
I think there are still reports here and there of other issues, but most of the electrical related stuff is because of the defective batteries.
I bought my XChallenge as an upgrade to the DRZ. It has been everything I expected out of it. The XCountry is a very similar bike to the XChallenge. Sort of a cross between SM and Dual Sport. The XCountry is not European made. I believe it is made primarily in China, but to BMW specs. The best part about it is the fuel injection - I'm done with carbs. I'm not sure the exact weight of the XCountry, but I would venture it is about 50 lbs lighter and has 20HP more than a KLR and still gets better mileage. I think it uses the same small fuel tank as the XChallenge which gets about 150 miles.
