Hi. I currently webcast sports events on ustream, however looking for
a better quality paid service without ads.

Just wondering if there are any opinions on this subject? Also, would
anyone happen to know pricing? I have looked at some like watershed
and Bitgravity. I am slowly leaning toward Bitgravity, but i dont know
anything about pricing from them

Any help would be great.

Thanks
