No experience with the frame but I know if you regularly check returned items on Nashbar sometimes one will show up and they'll knock a few hundred $$$ off the price. You have to act quick if it's in a desirable size like 56 though.
They sell guerciottis too... I have no opinion on them because I have no experience, but the guy I bought my Lovell from said that many of his friends raced on Guerciottis in the early 80s because that's what their sponsor provided -- he said they all hated them. That surprised me because I thought they were fairly well regarded.
Again I have no first hand experience with this, this is all hearsay and is inadmissible to prove the truth of the matter.
