Good points about shop vs multi-tools. When the op mentioned commuting I assumed they were looking for a portable kit.
I agree with GuitarStv that it is good to acquire the tools you need as you need them. That said, the amazon link that FLBiker posted looks like it covers most of the basics for a reasonable price. However, some of those tools look a little cheap.
For example, that ring-shaped spoke wrench has sizes that you'll likely never need, and it's form is such that it lends itself to stripping spoke nipples (at least for me). I went with this a
Park triangle style and have used it for many years.
As well, I get frustrated with the L-shaped allen keys and use a 3-way allen wrench 90% of the time. Similar to
this one.
Lastly, those little driver bits are super annoying to me. I prefer to use real drivers when I can.
