It's a bit of an epidemic, people go out and pay as much as possible for new parts, throw them on a banshee, never ride it, then try and recoup their expenses. Sure it may look pretty and the parts are nice but the second they're not new from a vender with a warranty or anything they loose value, couple that with a down market and you are out a lot of money. Most people also like to have a hand in making their bikes nice, not buying one already done up from someone else.
You have to accept this fact when you build it and either get your moneys worth out of it or ask yourself why you did it in the first place...
