The V-Strom's pathetic electrical system is part of a grand tradition that goes back many years. We have the exact same litany of problems over on the vintage Suzuki forum, TheGSResources.com .
Although I have to admit wandering stator magnets are a relatively recent innovation in electrocrappery... it's a damn good thing the bikes are so much fun to ride.
Anyway, the Polaris series R/R has a lot of fans over on The GS Resources forum, and I haven't heard of any problems at all, other than they're sometimes backordered for a bit (someone at Polaris is probably worried sick trying to figure out why the hell so many ATV regulators are being ordered...). If you dig around, you can even find a thread with temperature readings, oscilloscope traces, and more.
