The Tantive IV Trooper came first, and I believe the Evo Sandtroopers were based off it then, but the belt on them was different perhaps? I can't recall now and my Empire's tucked away at the moment.
I have probably a lot of the 30AC Stormtrooper with the lopsided legs, but I got them insanely cheap. I couldn't pass them up for $1, $2, or $3... I have a lot of basically every Imperial in white because of sales and clearances back at that time. Really went nuts.
