For the best support + history:
www.isprime.com
or
www.realitychecknetwork.com
I have NL boxes with both of them - they're very good companies.
They understand growth, have REAL 24/7 tech support via ICQ / email / phone
Essentially, they're proactive hosting companies, that actually look after your shit, as opposed to those that let it break, and then scramble to fix it..
