There's a cheaper way to look around and that's with an OS inside a Virtual Box machine (see google, price? can be free.)
Also, google up the TAILS OS which can run from USB or CD and is nearly bullet proof. Especially run from a CD/DVD.
I'm researching several subjects in Asia, especially China. After the story about malware found in Comcast routers, I'm a little leery of surfing Chinese websites such as main news sites, Chinese military sites, etc.
I'm working on getting a used computer specifically for this purpose but are there any recommendations for a person who will be visiting sites in Asia or am I just being too paranoid?
