My Gios ('78 or '79) rusted horribly, even after the repaint. Gios paint always had a bad reputation, but it was otherwise a nicely made frame. I appreciated that the lug points weren't shaved down, the better to stand up to repairs.
I had the opportunity to work on a Serotta 7-Eleven team replica a couple years ago. The metal work was lovely, but one look at how the seat and head lugs were "relieved" and sculpted, and it was obvious these frames wouldn't hold up on Belgian cobbles, especially under the likes of Bob Roll. Still, I'm sure it would be a nice ride on smooth US roads at moderate speeds.
My California Masi looks and feels like a workhorse, a balanced all-around tool for the amateur rider who had to buy his own equipment. That gets my respect more than pantographing and chrome.
But if a 58 cm DeRosa fell into my lap, I'd probably sell my Madone to fix it up.
