After a few months with the pro it finally happened. I reached in my pocket to take out my stylus and it wasn't there. I searched everywhere but I traveled to many places today to backtrack everyplace. I've seen posts about alternative pens, but they all seem to be lacking in some way or another. I haven't seen an alternate pen that offers an identical feature set to the SP OEM one. Most either lack eraser functionality, alt-click functionality or are not nearly as pressure sensitive. I checked Amazon, but the only OEM stylus I saw listed was $44.99 ... which is a bit ridiculous :/. Is there a cheaper store some where online for a replacement OEM pen? Or am I just SoL?
