The NATO brass button compass by Pyser (from Bestglide and others) seems to be the gold standard.It is some what expensive.
www.survivalresources.com has high grade plastic button compasses.Then there is the SUN micro compass of which is a small base plate model with a rotating bezel.Then there is the compass in the PSP and PSP+ by our very own Doug Ritter.You get a lot of good stuff to build off from.....
