Flatrabbit?
I'd love to hear the back story on that name...
Welcome to the MEPD, home of SW sandtroopers.
You can do some homework by visiting the FISD and reading up on the "history of armor". Also, depending on your location, try looking up your local 501st Legion Garrison.
For TM armor, you can contact him directly.
I don't know how to contact AP, but if you're interested in TE/TE2 armor, I invite you to drop me a PM anytime.
The important thing is to enjoy your journey regardless of the armor you finally decide upon.
Aloha,
T
