Craigslist.
Bought a R300 Cannondale frame for $60 off CL (fork tweeked).
Performance carbon fork was on sale, couple little parts and Kane Creek headset with a 15% off cupon on top of it was out the door for under $125.
Bought a very low mile Novara Trionfo with a Full 105SC group and good tires for $125 for the rest of the parts I needed except the 44cm bars I had.
Nickel and dime stuff including cables and tape $70
Sold the Trionfo Tange Prestege frame and Fork for $75.
So $305 in the bike.
