I received notice from Guitar Center and a few others for "Pre-ordering" STRIKE Individual Kit pieces about a month ago..
I see they are starting to showing up in stock,but it would be cheaper to purchase a whole kit.
I have purchased a number of kit pieces NIB on eBay from stores parting out kit's.
Attached a copy of Alesis individual pt# and retail prices so you can get an idea of buying piece by piece..Dealer/Dist etc are blurred out.
