This is where I've been getting my customized truss rod covers and poker chips...
Truss Rod Covers - Custom Engraved - Page 1 - Philadelphia Luthier Tools & Supplies, LLC
It looks like they offer parts that fit Ibanez, Schecter, etc.
And yes, it's totally worth the $12 a piece having two truss rod covers with "Dickhammer" on them
Also, the turn-around time is typically about a week, and I haven't had to deal with their customer service yet, since everything has come out spot on, and everything has fit perfectly so far!
