Diagonal discrepancy!

Hi,
Hope someone can help me with this:
Andrews has a GSO quartz diagonal listed as...
Diagonal, 2", dielectric, QUARTZ, 99% reflect., 1/16 wave, 90° $139.00

Whereas Bintel has the same diagonal as 1/12 wave 99% reflectivity $149

I assume that this is the same diagonal - why the difference in wave data, does it matter - is it negligible for visual use? Have Andrews misprinted?
So many questions!!!!
Cheers
Doug

They are probably both only 1/10th wave, which would still guarantee them to be excellent performers.

I have the gso 1/16 wave diagonal from Andrews. Its absolutely brilliant. If you can get it for $139 then go for it.

I'd guess Andrews has better, cheaper gear in this department - no surprise there huh?
