Choopa.com is the best, I've been with them for about 2 years now
Right now this is their special -
P4 1.7ghz
512mb
40gb
3000 gigs (10mb/s)
$500/mo
That's capped, but if you wanted it uncapped, it'd be $750 per month.
Their bandwidth is only the best Tier1 quality stuff, NO Verio or Cogent crap. PLUS their network is huge 9000mb/s which I don't think any other host can compare to that.
PLUS to top it off, the people there are great, Dave is a good man and their support is excellent.
