Well, there probably are, but my (little) experience is that the 
usual ones you get have a 20-25% tolerance.An MKT 2.2 microF costs
around 3-4$. My believe is that price will increase quicker than 
% tolerance. Indeed I do want them for a lab session where I need
10 + (10;every student breaks his capacitor) + ...same old story.

Any way, I will consider to have them  measure L in a earlier 
lab session with such a resonant circuit.
