Nice list.
Ill also vouch for Ultrafire F13. First generation of these had pill. Second generation, which have been the lights sold lately seem to be unihead/pill less.
Small Sun ZY-T13 (middle section with pill is one part)
On the Road X6M (middle section with pill is one part)
K2 does have some sort of pill. There are several solarstorm lights that seems have a tight press fit aluminium pill... Including the smaller modes.
As for blackshadow. Im not sure if they are all pill-less. But they are not all good. My blackshadow padme have a mostly hollow pill. Terminator does not have aluminium everywhere under the emitters either. Its up for debate, but id say its good. You be the judge.
