I've been trying to buy a fully functional brake booster for about 7 months now. Every brake booster I've bought online through eBay has come with a leak inside the diaphragm. I seriously cannot find one good working brake booster! Would rebuilding my current one be a viable options?

Did you look at NAPA? They do have one for a 240D. They are not painted though.

I sent mine to Prior to get rebuilt. They work through rock auto For 100 bucks it’s leak free

Be sure that the seal (O ring) between the booster and master is new. This is a common oversight, and many boosters have been returned needlessly.

What Rich said X 10 ! .

Amazingly it's possible to run and drive the car with this special O-Ring completely gone missing .

Rebuilt boosters are out there, I've had good luck with the junkyard ones .

If you can find a kit, it's easy to rebuild a booster.
