Maybe just a bad batch. I traded my ct7850 months ago for a milwaukee. I have been more than pleased with mine. By the way I also just bought the bare tool.
You could maybe get away with buying the socket set and renting the tools from your autoparts store. Brakes aren't that big of a deal. The ac is where you might do some research and see if your up for the task.
Start with a craftsman mechanics tools set that has 1/4,3/8 & 1/2 drive sockets and ratchets. But of course I would wait until said item is on sale. Then fill the gaps and extra hand tools from HF.
Busted a cheap 3/8 ratchet and cut my knuckles in the process. Bought a 154pc craftsman set. It made a huge difference. Also first time I had all my sockets and wrenches organized in blow molded case and not just in a box thrown in.
