Aluminum Coating or Silver Coating?

Not really a building question, more of a re-building question.

I have a C8 that needs the mirrors recoated. Celestron is asking $325.00 for this which I feel is fair but in the interest of economics... (I am scope poor)

Majestic and Spectrum can re-coat these mirrors for 1/3 ($90.00) the costs except silver is more in the Celestron price range.

Silver or Aluminum 98% -vs- 91% reflectivity..?

Can the main mirror be removed from the mirror cell on an SCT by someone without the factory tools to re-collimate?

Thanks!
