Oh man! Steel Saber! YES! I hope the other Mech suites make it in there now. cool
These come to mind off the top of my head:
VFM-01F Stryker-F
Ivangelia
Cybernetic Legionary
Maid 4 U
I'm loving the way the shop is operating now. Any chance we can see Sharktooth show up? There are quite a few anime with characters with that grin and sharp teeth.
