Air tools FTW.
If you work on your car, it's just something you have to buy. I got my compressor and impact driver when I decided to do an ITR suspension conversion. You can get a decent compressor at Sears for pretty cheap. I got mine on sale for like $120 and it's more than enough. I snapped an LCA bolt with it once by accident. Good used impact drivers are all over eBay too.
You can get in under $300 easy, and the tools will pay for themselves the first job you do, vs. paying a shop to do it because you couldn't get a bolt loose.
once you have air tools, you wonder how you ever did anything without them. It makes working on your car so much easier.
