I live in Michigan and have mailed stuff back and forth to M_S before. It usually takes about 2-3 weeks for the mail system to actually get it to its designation.
It can be frustrating at times but at least the end product will be worth the wait. I have one of the MQ-1 calc guts he sent me a few months back. They are very clean and very crisp with detail.
They will be to you before you know it!
