Congrats on the new ( I assume) SP1, but no pics? Thats just torture, man!

I owned one once. Had it converted to select fire. Long gone. Still have a couple of SP-1 uppers.

What did you pay if I may ask?

The early SP1's are fast becoming "Curios and Relics." We're up to 1969 vintage now. That means they can be sold interstate to anyone with an 03 FFL.
