If you want to pay for the Samsung logo, wait until it's being sold. If you want to buy the same thing without the logo, and save almost 100%, there are puck style chargers all over the web for under $10. Look on eBay. (Qi is Qi - you don't need a specific charger to charge a Qi phone, just a Qi charger.)
(You could also get a PM charging pad if you want to stay compatible with a standard that's probably going to go the way of Beta video tape, the way Samsung is. [Even a company as large as Sony had to give up and switch to the industry standard eventually.])
