Scrap Yard does a build of a particular model, announces a sale date and time then accepts e-mail orders till they are gone. Sometimes it's a one time build.
You'll have to look on the secondary market now and also pay higher than the original price since there aren't anymore and may or may not be built anytime soon.
If you want a big 9" chopper, go for a Ranger. You'll have one with custom features of your own in 2 weeks or less.
