I've been waiting for the S2 head that is replacing the R2 head I sent back. I PM'd Stan, and he said that a large batch got shipped out on Monday (i.e. about 2-3 days ago, depending on how you are counting), so I am guessing both of ours should arrive within the next few days.How long did it take for you guys to receive your att from date of purchase? I ordered a S2 on the 16th and the only notice I've received is that a shipping label has been printed
