Well...if you look at it this way, ANY other place is like $400+....because every and anyone else I have called that makes aftermarket grilles do not see it as a money maker, and they look at it as a 'one off' even IF I prove that there is a small market for it they will not bring the price down....they do not see it as a money maker.
Also, if they can reproduce the factory grille, they might be able to make it somewhat custom. Not sure what kind of custom anyone wants, but it maybe possible for them to make it a bit custom after they make some initial run of grilles. Then you have to factor in the price of the factory grille. The factory grille is about the same price....and you get the chrome that chips, cracks, tarnishes, and you name it. Not to mention that if you hit a rock at terminal velocity with the grille, you end up with a grille that looks like the one on my car......or used to look like.....now I have none....I tried to fix it, and modify it and the cheap a$$ed plastic busted in my hands....I purchased one off of ebay (knowing that it was not perfect.....I did not really care because I was gonna make a custom one) and it too fell apart while I was attempting to customize it.
So, giving all of those, that grille does not sound like a bad idea. If nothing else, and if they can not, or will not do custom ones, you will most likely be able to customize it yourself (with minimal effort) without it breaking. Then you can paint it, chrome it, powdercoat it, or do what ever you like to it, without the possibility of it falling apart in your hands.....well, at least not like the factory ones. So, this grille has MANY possibilities above and beyond the factory look......just my $.02.
