Hostingsource seems decent overall; good uptime and fast support based on most reviews, especially on their AMD servers.
Just double check the contract terms before signing; even with "no contract" marketing, dedicated plans do have a minimum commitment period with an early cancellation fee, so get the exact terms in writing first.
For any AMD provider, I would compare a couple options on uptime SLA and support response time, and try a short trial if they offer one before committing long-term.
