Samsung will replace the whole display assembly for $191 (including shipping) so I wouldnt recommend spending more than that! I've been looking into this myself as the wife just cracked the glass on hers. LCD and phone still work fine, it's just the glass, but unfortunately they are all fused together. Been looking at them on eBay (US sellers only) and there are some for around $150. Going to tear down her phone first to make sure what they are selling will work without having to use a heat gun and all of that mess.
