You're thinking brand new for sure, or would you consider a year or two old?
If you're doing any freeway or anything, I'd stay away from the 250 or 400. A used KTM LC4, like a 625 SMC or a Duke are as bulletproof as a DRZ, but fairly heavy(~300lbs). I just sold my Duke last fall, best bike I ever owned, but to race it was just a little heavy.
If I was buying another reliable street bike right this second, I'd check out the new KTM 690 SMC. The thing rips, looks like a proper SM, and is high quality.
The Aprillia's are to racey to hold together very long still, but they sure look and ride nice. Husky is another great street option, like the 510. That or the SMC would be my top two new ones.

, in their buy/sell section. You're in a good part of the country to get something used but mint out of Florida, I'm jealous.
I'm pretty much forced to drive 1500 miles across the border to find anything this spring.
