Looking for any suggestions on these needs:
- 30 gbs of hard disk, Linux, vBulletin forum.
I would like to know your views on Tzulo.com and QHoster.com web hosting plans?
Is this host reliable? Any info about them?

KVChosting.net and owned-networks.net plans are nice and they have many useful resources which can be suitable for you.
They truly have the best services. Not to mention, great speed and amazing support.

Plans from hosting.uk and owned-networks.net are good for meeting the needs of any webmaster with a tight budget.

All my questions are answered quickly and promptly, and Tzulo.com hosting service has been excellent.
I am able to focus on my business instead of worrying about my site's uptime, since all that is taken care of very well.

Well, Tzulo.com has been a great experience for me. I did a lot of searching before I picked my host and this one looked to be the best pick for me.
Their support responds is within minutes (although i never had any major issues).

Plans from brixly.uk and owned-networks.net (ONHOLIDAYS)can be suitable for you.
Best hosts out there so far. Great service. No hassle.

I would like to say that Tzulo.com does offer a very good price and on the half dozen or so times that I have needed to speak to them, including in the middle of the night, there has always been a technically competent support person available immediately.
