I go through the same question when I pick up a new bike. In the end, I usually just recondition. Since you want to sell a bike to the highest bidder or if you want top dollar, it's good to know the philosophy of the C&V community and most don't like resprayed high end vintage Italian bikes.

My issue with the repaint is, who painted it? Most individuals are selling a repainted bike for top dollar and I loose confidence when I don't know the painter.

I personally love CycleArts work. I would and have owned a few bikes that they have repainted and are fantastic. I would pay more for that bike, but again I would prefer original. I don't like the painters signatures on the bike however.
