Best proxy to use with the senuke program?

Hi guys
Newbie here and just hoping some of you can help me with a dilemma.

I'm planning to use the program senuke to help drive some of my blogs online and I need a good proxy which is going to let me post from multiple, interchanging IP's.

Preferably one which isn't slow in it's functioning.

Can any of you guys point me in the right direction?

Thanks in advance

I have used TrustedProxies with good results, they also have different GeoIP's that can be useful.
