We've had a great experience with dedicated servers from MangoHost. They offer a variety of configurations — from entry-level setups to dual CPU monsters — and the pricing is far more reasonable than most “premium” providers.
Their support team is responsive, and you can choose data centers in Europe or North America depending on your audience. Plus, they allow OS customization, RAID setups, and even offer optional DDoS protection — great if you’re hosting critical services.
