VPS or Dedicated
Are there any VPS sites here running a vBulletin forum that averages 50 to 75 users online that would care to share their expieriences and what kind of response do they see.
i would expect that a medium spec vps would do you fine for this amount of users, 128mb ram would be more than sufficient, and 50-100gb bandwidth
If you want to test choose VPS and want to a stable system choose Dedicaded.
