For what it';s worth, I picked up the final Santa Fe F3 last night, the 19C. (A week before it was scheduled to arrive!) This means all the current F3's have now been delivered.
Everything seems to be OK with it, still have to scalify it.
I'll have a concluding post about the Santa Fe A-B-B-A set when my lead F3 (#18) comes back from repair.
