I've had a chance to look over the Bullion-Master charts of the silver companies from Scone's post. For the most part, I agree with the technical assessments provided.
For what it's worth (and once again I make no claims of being a great stock picker), the ones I think have the best bang for the buck and are near good entry points are EXN.to, GPR.to, MAI.to, USA.v, & SLW. Tomorrow, I plan to buy EXN & MAI - the rest, I already own.
