Update:

Thanks again everyone for the discussion! I actually came across a used pair of M60's V2 which I couldn't pass up - even though I've never heard an Axiom speaker at work yet! The fellow was selling the pair for $350 and it cost me $40 for shipping materials + another $100 to ship to Canada.

All in all, a good deal - the grilles will need replacing due to "cat attacks", but the important stuff is excellent condition. I'm sure I can get replacements from the factory.
