they pop up here on the site quite often and quite a bit cheaper than that. to me thats too much money. they don't come with the flapper set up and i didn't think they had casting numbers on them if that matters...
i don't know of anyone that has tried them. never saw any posts on any of the forums i'm on about them. thats probably a good thing..lol
