Best Hosting for WordPress Required

[Jodi]

I run about 10 WordPress sites. Some are more complex than others (1 is moderately intensive).
I'd like to host all my sites on the same platform, rather than have 1 here, 1 there, etc. I can spend up to $40 a month on hosting. So a few questions:
1) Are there any "premium" shared/cloud hosting platforms out there (I know that sounds like an oxymoron, but some shared hosts are better than others).
2) Should I look at Managed WordPress solutions? Any recommendations?
I am looking to upgrade to something more WordPress friendly. (currently paying about $25/month).
What can you say about Regvps.com hosting solutions? Can I rely on them?

Thanks!

Trustworthy hosting plans are available from allwebhost.com and hostsailor.com.
They are VERY reliable and whenever I have had a problem - they solved it. Pricing is good to say the least.

VPS hosting is necessary for those who must have confidence in the fact that guaranteed resources may be received at any time, but temporarily cannot purchase a real dedicated server.
I had a few problems to set up my new account, but thanks to the awesome support of Regvps.com finally I managed it. Their support is outstanding. Very fast and friendly.

VPS accounts from hostingsource.com and rockhoster.com are worth your attention due to their unmached services with high uptime and quality support.
Absolutely incredible. Moved over to them and couldn't be happier. Really solid tech support team, high speed servers, and great customer service.

I've used a lot of hosts in my years. So far, Regvps.com is my favorite. My Los Angeles vps was up and running within 12 hours.
The support replies within seconds. Best of all, my site is noticeably more responsive. The system itself is rock solid and the software & features are excellent.
