Where to buy MP3 Players

I've looked at 2 of the usual suspects like Airport Plaza and Tesco, the latter had no MP3 players and the former only had the larger ones. I'd preferably like an Ipod Shuffle without a screen (which is all I could find at Airport Plaza) something like this: http://www.lazada.co.th/ipod-shuffle-2gb-silver-103918.html

But would also be satisfied with a Sony like this: http://www.lazada.co.th/ipod-shuffle-2gb-silver-103918.html

Both are out of stock at the online store (support doesn't know when they'll be in) and in any case I'd rather get to hold one instore and try it out before purchasing. In case anyone asks why I don't just use my phone it's because I'd like to have an MP3 player for long haul flights and travel and want to preserve battery life on my phone.

Any suggestions on where to buy here in Chiang Mai?
