same boat here. had a wr250r for 3 years, and did an offroad trip where i wanted better suspension and more torques.
i ended up getting a 450exc RFS ktm. you shouldn't rule one of those out, they're very durable for what they are. and WAY more fun than the wr (don't flame, i loved mine, i just wanted MORE, and i'm not racking up huge miles or anything)
