Solen vs NCMS inductor....

Guys,

I am in the middle of buying XO components, and need some advice regarding the price & performance of (air core, wire) inductor.

In terms of performance (sonic quality):
Which coil is better? Solen or North Creek (NCMS) ? (for same AWG size)

In terms of price:
Which coil is cheaper? (for same AWG size).

I have a very limited budget to make a DIY speakers, so I want to make a comparison first before ordering the coils. I looked in solen website, but no price listed for their coils.

Thanks,
