Hi Tony,
Sentinel's main business is figures - check out his three web sites. If you THINK you MIGHT need it, Neil has it.
Also, Neil is a very nice gentleman and and a fellow painter. Neil is my main "fix" for all my painting needs, and I owe him a great debt since he taught me how to use oils. His location is even pretty close to you if you want to visit (call first!), though he vends at most of the main figure shows.
I have used PE stuff with pretty good success - both as glue-on heraldry and for tracing or making a paper sitck-on. I can't draw - hell I can barely write! - so I keep my ears tuned for any shortcuts. PE stuff is expensive, but it will last a long time.
Good luck!
