If you're just getting the twins, and won't be able to avail of any free shipping offers, I'd consider getting the
Werkstat products instead - they're based on the same formulas as the Klasse twins, but more advanced. Prime is the updated version of KAIO, Acrylic Jett is the equivalent to KSG. Also worth considering would be Acylic Jett Trigger, which is basically KSG in a sprayable form. Best part is, they're actually cheaper than the Klasse equivalents, and (excluding any sales) ship at a lower cost than they would from Autogeek, too.
