I'd go for the new one as the price is comopensated by the fact that it will be more energy efficient, the bills hence will be lower and/or you could use it not only for a longer time -in terms of years- but a longer persiod during the day. Moreover, there is a 2 thousand nt "kickback" from the Government/Taipower when you buy a newer one, so you will be saving 2K already from the start.
Do not go to the big yellow store. Even a smaller, neighborhood store would be better, in terms of service.

If any new arrival needs assistance in Taipei, I can provide it in exchange for Star Trek or Supernatural
(the TV series) stuff or other sci-fi materials. Let me know what help you need by PM, along with what you have to offer in return. And yes, I am serious.
