I have a $20 Super Program that got a CLA for $55.
I have a Free (dad gave me his) ME Super that cost me $55 to CLA.
Got an ME Super for cheap ($30) for my fiancee. Sent it away to be fixed and cleaned. $80.
Had 50mm 1.4 Pentax lens, 135 Takumar Bayonet, and 135mm M42 lenses all fixed up for about 50 each.
Electro 35 cost me $60 to CLA, $24 purchase cost.
Kodak Medalist went to the fixit guy. Cost me $280 for CLA plus fixing a broken finder window.
Kodak Autographic Brownie No. 2 from about 1919: got it for free, spent $65 to have it brought into shootable shape.
Now I have a sick Leica M2, and I'm going to eventually send it and its collapsible Elmar lens off to be serviced for around $500-600 total. Only cost me $100 though 🙂
These prices may seem silly, but if you are going to shoot it, it pays to have it gone through. Especially when you consider how many of these cheap cameras you'd likely go through on eBay before you found a good one, and even then you don't know how long it'll be before it gives up. That adds up quickly.
