Is it worth replacing the corrector of the ETX90?

I have a Meade ETX90 OTA and the aluminium spot on the corrector lens is defective. The outer parts seem to be oxidized (I see colorful rings) but the optics give suprisingly good images. The whole corrector should be replaced but as far as I know it is not possible without replacing the matching primary.

Is there anyone who could give me an estimation how much Meade would charge for replacing the complete optical set? I wonder if it is worth at all :C , supposing I could buy the OTA for around $150 here, on Astromart.

Thanks,
Levente
