I made a thorough analysis recently and discovered that catalysthost.com would give me the best value for money. I am using a "Trenta" OpenVZ Ubuntu 12.04 machine for $15.99 per month and I am quite happy with the performance, including network performance. This is the spec of the vm:

4 CPU Cores 2GB RAM 512MB vSwap 60GB Storage 2TB Bandwidth @ 1Gbps
