ava.host is the sister site of alexhost.com, while I've not experience with ava.host, I have had a fair bit of experience with Alex Host and typically don't have anything bad to say about them, VPSs start at 4 euro with unlimited bandwidth, can't remember storage, but 100mbps connection.
If you're needing 1gbps or more but offshore, ZetServers offer 1gbps - 8gbps servers and it's who I currently use for proxies and had very little problem with them over the past 12 months, however they do start at 30 euro a month for their base VPS plan.
I have recently moved from Alex Host to Phanes Cloud as their a little cheaper and I think they must have less VPS's per machine as I typically get 300mbps speeds even though it's advertised shared 1gbps. They however have limited bandwidth but for my needs they're perfect
