I completely upgraded my old steel columbus tubed Bianchi with modern shimano ultegra/105 and it's a dream to ride. Comfy, fast, looks great, and its 100% reliable. It doesn't jump off the line or float up hills like new carbon or aluminum bike but it chugs along at 25mph quietly, comfortably, and it's very stable. The entire build including bike was under $600 (though it took some pretty clever shopping)
