Mostly for bike use so M3-12 would be fine. And I guess with bikes it would mostly just be steel and aluminium. It looks like there is a flat head screw driver in there, does that mean you can drive the taps with it? That would be useful for things in tight spaces. Actually I guess that's for tightening the thing that holds the dies!
But yes 27 pounds seems like very good value, I would probably be happy to spend a bit more for slightly higher level.

Just replace the cutters with high quality ones if/when you wear them out.
For bikes, you only really need M4-M6 in metric coarse taps, plus an M10×1.0 tap for chasing dérailleur hangers. Anything else you're not going to be making/repairing.

A ratchet T-handle is a good thing to have in your arsenal for tight spots, e.g.

What sizes? What material are you going to be cutting? Standard sets may not be the best choice.
I'd probably put this one in my tool box if I had no idea what I was going to need
