It depends on what the CLA really consists of. If he does more than just clean the shutter for that price, it may be justifiable. Even though as, Ian says, this may be a routine thing for a competent camera tech, I think one should be aware that cheap CLA can become more of a hassle in the end if the repair person is not up to the task.
I have a Rolleiflex Automat which I sent for a service of the shutter and the stiff shutterspeed/aperture wheels. I sent it to what I believed was a competent (and cheap) repair man. Well, the camera came back in even worse condition! Writing him off the list, I then had another guy look at it. Camera came back a second time, a bit better wheel function but shutter still sticking (!).
Exasperated, I put the camera on the shelf. In the end I couldn't sell it (being too honest to flog it as a Mint minus condition on ebay) and it just seemed to be non-repairable. Half a year later I got a tip in another forum about Jürgen Kuschnik, former Rollei tech. I packed the camera a third time, thinking "the h*ll with it, if it doesn't work when it comes back, I'll throw it out the window".
Jürgen stated clearly what was wrong and what it would cost and possible future issues to think about. I gave a go-ahead and yes. third time's the charm! Camera works as it should. It cost me some good money, but now the back is straight, shutter and self-timer works, focus is adjusted, film transport smooth and lenses clean and clear.
Yes, it is quite possible that I could have gotten the camera working by going back to repairman A or B but hearing a few others complaining, I had lost my trust.
I understand if $145 and $195 sounds a bit much. I think it is relative to the value of the equipment and to the value you yourself put into having a working camera - had you bought the Rollei for say, $2500 and depended on it for food on the table then the CLA would be "cheap". With the dminishing value (both actual and perceived) of the cameras the CLA prices will be less and less attractive, possibly giving way to "buy another for $5 instead".
