I just picked up a set of 9-speed Sora STI shifters for $69.99 on Wiggle, they're having a January Sale with lots of Shimano components included. They also have a $10 off purchases of $50 or more for new customers with a coupon code Wiggle10. My shifters ended up being $58.71 out the door somehow. I have been looking at these brifters for a while and they are like a hundred bucks more on Amazon and not nearly that cheap on eBay. Anyway, just wanted to pass along this deal to my fellow riders who who might be doing winter a build.
