Picked up the M12 Riveter from Acme Tools - debated a lot on this one (pneumatic vs. battery), and decided to opt for the battery one as I already have the M12 system, and it gave me a little bit of flexibility in the future (not having to drag an air hose when using it).

I also ordered 100 each of the 3/32 and 1/8" clecos from Cleaveland, a couple more 1" scotchbrite wheels for the angle ginder (which are most useful for skin and lightening hole deburring), the rivet-gun dimple set adapter (just in case), a 4" no hole yoke for close-quarter dimpling, and another countersink cage (to prevent a lot of wasted time setting up the 3/32 and 1/8" countersinks.
