I've bought from Applecart (and know him informally) and had no problems.
I bought a 1973 Eisentraut from him, full campy for less than $300.
Yah I gladly paid the $35 packing fee. Bike came with all tubes wrapped in foam pipe insulation
and then bubblewrapped. Fork was properly blocked, not just at dropouts either.
Although it wasn't double boxed, there was plenty of additional cardboard reinforcing
the box. So for me it was worth it. Ok, not a fixie, so I can't comment on the Locktite.
I bought a set of campy tubular rims from Bensbike, and by mistake they sent
me someones new mavic reflex rims (the ceramic high zoot ones). I contacted
them and they asked if I minded shipping to correct buyer. Then they sent me
a 20 dollar bill wrapped around one of the rims to cover the shipping.
First class all the way.
