So far I've narrowed it down to the following:
http://squidproxies.com/ ($24 for 10 private proxies - all in one city)
http://www.newipnow.com/private.html ($5 for two private proxies -2 cities)
http://www.proxy-pimp.com/ ($2.50 per proxy - can choose from New York or Seattle)
This is for creating two Facebook accounts - so I'd like to go with someone really stable (because I'll be screwed if the proxy goes down and I can't get another in the same location).
Does anyone else have any suggestions - either from these three choices or someone they've worked with personally?
Thanks

not private but anonymous 
you dont need private proxies for facebook, just reliable ones that are in the same country. Over the last 3 months I have accessed facebook from about 5 different countries and 3 different VPNs, and the only times it flagged up to me and needed some additional authentication was when i changed countries.
So as long as the proxy is in the same country as the address used in the account, it should be okay?
What is the difference between a private and anonymous proxy?
I just want to make sure I got this handled for when I create these accounts 
Did you see Polarbacon's post about getting a facebook account after being banned?
private proxy gives you a unique ip that is not used by anyone else for the time that you have the membership. Its possible for private proxies to leak your original ip for certain providers.
anonymous proxies are used by different people simultaneously, but never reveal your true ip, and even if a C&D would be issued you remain anonymous.
so anonymous is better if you do seo comment spamming, blackhat, shady type stuff.
Yeah, I saw that thread - I must have missed the part about the location of the IP in accordance to the account.
Thanks a lot for the explanation 
I use http://hidemyass.com which works fine for me.
Ok just so ye know....proxies can be a bit of an issue....the CC info zip wise needs to be close to the ip's location....
if not after a short while you will get the "fraud check" (atleast I do)
I have a dif plan in the works.....I will be goin thru this in a tutorial at some point soon.....just need to work out the finer points...
Any solution for PoF?
This one is good :
http://anonymous-proxies.net/
thats a nice source, but this made me laugh.

ive started setting up my own proxies using cheap vps'
that way i can pick the locations and make sure its not an obvious dc ip
using socks5 proxies. seems to pass all the "proxy" checks.
Hey tjin,
Please can you explain a bit more on how you do this? I'm trying to find a similar solution.
Thanks in advance
what kind of software you used for sock5 proxy
