Looking for 1" 1/4 swing gate check valves

[FishFun]

I checked our HD & they dont have a 1"1/4 & the ones they do have use brass. I tryed the plumb shops & they dont have either, they just just look at me funny & wonder whats wrong with me for haveing such a large tank that needs such a big check valve , I never tryed the spa shop though! They dont need to be clear but it would be nice. Wendell at Ocean Aquatics got back to me allready (talk about fast service) & he would need to get 36 of them in order to get me one. So im still looking!
