space shuttle - $1800... are you high?

Ok, so I have a space shuttle myself.  I bought mine for $400 about a year ago.  I've replaced power supply, the sound board, I have a brand new playfield/plastics, brand new ramp and shuttle, new backglass, flipper rebuild kit, new rubbers, probably spent nearly $1500 in parts alone (I plan on repainting the outside cabinet with a stencil kit, add another $150), and yet.. I... that's right, ME.. I DON'T EXPECT to ever concieve to ask $1800 for mine when I'm done.  This guy is trying to sell a working space shuttle, worn playfield, replaced shuttle (ooh, $42 big spender), and you want $1800?? seriously?
