The downtime UA is still not up to snuff in my opinion, but it's better than nothing. Before, we had something like 1gp per day of crafting. Compare to Pathfinder where you can craft 1k gp per day. [@Cardamonelaw]

[@The Grey Dust] I can only assume the info is in the DMG to sell more books or to not clutter up the PHB with another 50 pages. Also because the majority of the items are handed out by the DM, and the Players shouldn't memorize all the effects and options (but they'll do so eventually anyways). Either way, cost of Magic Items is not written in stone. 500 gp is an average equivalency for most Uncommon effects, but some will be more or less expensive depending on a huge array of factors. Consumables, for example, are suggested to be half price, while it makes no sense for an Uncommon +1 Full Plate to cost less than a mundane set of Full Plate. Cost also depends on things like availability, the knowledge of the seller and buyer, and other factors.
