I used the term Pathfinder, and this is a D&D 3.5 game. As I don't have access to the DMG, or even the player's handbook for that matter, and I was told that the rules in both systems in creating/prices for magic items are virtually identical, I went to the Pathfinder SRD and looked up the spell there. So far, with only minor exceptions, again, the list and level requirements are virtually identical.<br/><br/>The 50K figure was quoted as 2*10*2,500" which comes to 50K.<br/><br/>But, as I said, the two systems are so close in the overall design that it's not worth detailing the differences, but as I haven't tried to make an item that wasn't in the list of magical items, I didn't know if that was the same or not.<br/><br/>Yes, 12K is well worth the item, and the time to make it is a little less of an issue as far as spending the coin and actually getting it while the game is going. I've been burned way, way, way too often by spending huge amounts of coin for something just before the DM drags the party away from that particular place and you never see it again... so you've effectively wasted all the coin you've spent so much time and effort making for nothing.<br/><br/>The time needed for making a 50K item is significantly longer than a 12K. Instead of something like a month, it's more like a week.
