Which Hosting to choose – Please Help

Hi ,

I am planning to buy vBulletin Suite.
I will be hosting a Discussion forum .

I need shared hosting service, which can support at least 100 users online

I was planning to go for blue host . But i have read couple of review in this forum, that its not good

Can any one suggest me a good hosting server. I want something in the same price range as that of blue host
