I'll get some pics on the weekend, and I just got over $60 of $0.50 purchases delivered last night. The DA Ravager is Protomech-size - looks like it'd give an Unseen Stinger or Locust a run for its money.
As well as the ones you mention - although I find the DA Purifiers a little small for a medium suit - the DA Grey Death standard and scout, Infiltrator II, Kage and Raiden are pretty good. The DA Longinus is a little bulky but works; the DA Achileus is kinda big (same size as the Longinus), and the DA IS Standard just on the cusp of being too big. The DA Kanazuchi is big, but because it's squat it works (it's not fat, it's just big boned ;) ) The DA Salamander is too big, but not unworkably.
Like I said, pics on the weekend.
