Colossus Light X - Quarian Colossus Med X - Human Predator Heavy X - Human Predator Med X - Turian Berserker X - Krogan
...can't seem to get good LIGHT armor for nothing. The place is a GREAT source of Serrice Savant X Amps & Omni-Tools, though.
I'll one-up your grievance:
Has anyone been able to get Tungsten / Shredder / Polonium / Proton (VII) Ammo Upgrades from the middle (75k) option? I've gotten Geth Armory Rage VII (krogan), and some crappy VIII guns, some VII / VIII tools / amps, and a slew of even more worthless VIII Ammo / Weapon upgrades, but no sweet VII's...
Too bad we can't trade items - I've got a nice set of Serrice Phantom IX that I'm not using (got a X from Delan!), and I never once got a Tungsten VII the whole way through... only a VI and a couple V's.
