if a camera or lens is purchased used
it is best to factor in a CLA into the price.
i find it funny that people think anything different.

i have no idea where you live but there are many people
who are good who offer a CLA at an honest price.
i am in rhode island and am lucky to have 2 great repair shops
within a stone's throw of where i live.

there is midstate camera repair and zack's camera repair.
i have used both and know both do wonderouswork.

good luck !
