wow, those three tools needed are like 10 bucks each, thats pretty expensive.
Just go to your local Lowes, Home Depot, Wal-mart. I think I got my Phillips at walmart, and the Torx T6 at Lowes. They don't really need to be of the highest quality, because how often are you actually going to use them?
ifixit shows three tools to replace the drive, what two do i actually need?
If anything, just make sure you're using a quality Phillips #00. The case screws are treated with loctite so the first time you remove them it will be difficult with a poor tool. You don't want to strip one of these.
if youre really cheap u can just buy from walmart and return it the next day
