Good Quality 10K pot?

I have some pots that i have connected to my arduino to control the color of LEDS via analog read.

One has already broke, (when i turn it it fees a lot looser than the other onese) and they will be adjusted fairly regularly.

I'm in need of some good quality pots, recommendations?

I have used these and am satisfied with there quality: Top image. http://www.jameco.com/1/3/potentiometer-10k-10-turn
