Subject: e/m demo tube with Helmholtz coils


We're in the end-of-year buying flurry right now and I have an
opportunity to buy an e/m demo tube with Helmholtz coils, sufficient
that a student can do the experiment and calculations to determine e/m.

What are the favorite brands (with their prices and perhaps pros/cons)
for you folks on this list?
