Anyone recommend cheap/reliable Class-C host?

I'm looking for a class C IP SEO that can offer 10 IPs at a cheap price and is reliable and hosting in the United States.

Anyone know of one?

Not sure what you mean by cheap, but IndiaNets do well for me. They use US data centres:

$20p.m. for 10 Class C's or $30p.m. for 5 domains per IP (50 domains). I have around 100 Class C's with these guys (among others) and they're reliable with good service.
