Here in Singapore, the 4167B is on sale in a few shops for S$105 (about US$64). No sign of the 4165B. Amazingly, some dumb shops are still trying to sell off the 4163B for S$99 (about US$60).
Last month, one shop had a sale where the 4163B was going for S$69 (about US$42). Apparently, there was a queue of people outside the shop wanting to buy that.
