Hosting recommendation for my forum?

[Appletalk]

Hey guys,

I run a forum that has an average of 50-70 maximum concurrent users.
For different reasons I have to move away from my present server.

I was looking at some popular hosting packages, like MediaTemple's (dv).

Do you think like a solution like this
http://www.mediatemple.net/webhosting/dv/

would be suitable for me? Or I need to go bigger?
It'd be nice to hear from your experiences or other companies recommendations.

By the way, speed is my main concern. The idea of having slow loading pages terrifies me
Both of internet connection and hardware.

Thanks,
Guillermo

edit: I noticed that there's a forum for this type of request. Feel free to move it. I'm sorry, I'm new to this place.
