How much speed are you looking for? Kawasaki has the new Ninja 300 coming out that looks very promising as a commuter and can be had for under $5k. That said I would place the Ninja 650 and SV650 basically equal. As said, see what feels best. Though I would take the SV simply because I dislike the way parallel twins sound. My current/first bike is a 1983 Honda Nighthawk 650. I'm probably getting an SV650/Gladius next spring. I keep trying to convince myself to buy the Ninja 300 but I bought a sensible car (2012 Mazda 3 skyactiv) I can't have too sensible of a bike.
