Where do I buy exclusive balls in Soul Silver?

Question

This was just bothering me the other day, because l wanted to catch my Mewtwo ON New Years day, so l could look in the information with appreciation.
I wanna know which towns sell Net Balls, Heal Balls, Dusk Balls, those types. A list would be very helpful.
