Why is the official Mercedes spring compressor over $500? Why can't one use the ones that cost 1/10 of the price?

Because they either won't fit, don't provide enough travel or they are simply not safe for the application. You can however, rent a Klann or a knock-off copy of one from several places (including a few members on this site) for a reasonable fee. Spring compressors are one tool that you should NOT compromise on. The penalty for doing so is often serious injury or death.

Does the $50 spring compressor work on Mercedes springs?

does the spring have to come out to change upper control arms?

123 or 126 chassis, no!

e-bay has several "Mercedes" spring compressors. I think I paid $200 for mine... works great and is quite stout.

On the 123 and 126 chassis the shock holds the spring in place by preventing the LCA from moving. To be safe it wouldn't be a bad idea to use something to prevent the spring from escaping "if" the shock or its fasteners failed for some reason. If you're going to replace the lower ball joint the vehicle can be positioned so that the chassis is supported off the ground and a jack or stand can support the LCA when the spindle is removed to replace the ball joint.
