The Filco is smaller and matte; the DAS is larger and glossy. You're gonna be fine, either way. I got Filco, because I prefer the size, style and it was in stock, while DAS wasn't.
Nothing wrong with saving the money. Though you should be warned, if you have more than one computer or type more than one place, you might end up buying another board, anyways.
Someone needs to weigh in on DAS versus Filco key caps, because that's the only other functional difference. DAS caps might be better (laser versus coated).
