good alternative to cloakfish?

iv'e been using cloakfish in the last 6 months,

but im not very happy with them, the proxies are real slow almost impossible to work under their proxies, also the US proxy list is not so good as they saying its almost always from same locations which is a problem, and the price is high,
$99 for 10k proxies a day.

im looking for good alternative with high speed proxies and more US proxies.
if someone can recommend on few places that i can get this service
ill appreciate that

Thanks
