Squidproxies are Sweet
It is a whole different world using private proxies compared to free ones. It actually doubled my efficiency. I did not realize that it would make THAT big of a difference but that in itself pays for the monthly service.
I don't know if you need private proxies in whatever you are doing but if you are using proxies at all you should definitely take a look at squidproxies.com, they have a discount I think too. Search here or other forums for the discount code, its like 20% off or something.
Just my two cents,
