It can be cool to check out what more products are available in Thailand before you buy something. The different digital products can have labels in Thai and it is not easy to read for a farang in Thailand.
If you looking for example for a TV then the Wikishop.com is an excellent example where you can dig deeper on different products cons and pros.
I have been looking for a digital professional camera for a long time and on shopwiki.com I found so much information on cameras that I now can buy one.
