I bought a Nashbar Double-Butted Aluminum Touring Frame last summer. With 30% off coupon, I paid a little more than $100 for it. Built it up with components out of the parts bin, which in my case meant Ultegra SL, and it's been a fantastic bike! Not the prettiest or the lightest, but a good, solid touring/commute bike. It has more braze-ons and rack mounts than you can shake a stick at, will fit 700x32 tires with fenders or 700x35 (maybe 700x38) without. I put 750-1000 training miles on mine, then rode it from SF to Los Angeles. Still ride it quite regularly...
