What do you think is the best VPN to get so we can check out landing pages for offers that are outside our own country. ie. you have a UK offer you want to look at but it redirects you to google or some other page since I am in the US? I have used that Firefox add on Header Spoofer but it doesn't work with affiliate networks that often.
I used witopia.net for awhile and was pretty happy with it. Some of the countries though would redirect strangely. I'd choose Austria or something and it wouldn't send me to Austrian Google, it would think I was from another country. Not 100% reliable, but overall I was very happy. Mass majority of countries worked great.
I went with hidemyass as I saw a few STM members talk about them in a positive light... some reviews I saw on the 'net were good and they seem to have the most countries covered and fairly priced. I just put it on one of my computers and it worked without a hitch... and it's one of my back-up to my backup computers too that is still running XP - lol.
Overplay.net..
Many senior affiliates using it. I use that too for almost one year, fast and reliable.
Overplay is the one I like the most since it's always pretty fast.
However I always keep also HMA active since it had a few countries Overplay doesn't have.
VyprVPN is also prettty good, but misses a lot of more exotic countries. I use it in combination with HMA.
Another thumbs up for Vypr VPN. I live in China and I think I would probably jump off my balcony if I didn't have a reliable VPN source such as Vypr in this country! Seemingly everything is blocked..... 
I have tried HMA and find that Overplay.net loading is the fastest! It can be use for mobile as well ! 
im using perfect-privacy its the best for me

I use Geo surf / Adclarity it cost some money but on other hand is highly effective.
