Given you have the dealer's agreement to pay all costs incurred (except that portion you are willing to absorb) and you have the option to talk to Magnepan after they examine the speakers to confirm the repairs will meet all expectations (i.e., the speakers can be adequately repaired) I'd go for it.
Allow me to add the warning that my perspective is potentially skewed by having lusted after various Magnepans for some time now. Unfortunately, my room would castrate them, a shame I'm not willing to endure.
