It's just usually Bandwith + Data has a really high impact on VPS price. So if you told me those are uncapped 1GB VPS I would change my judgement.
Where I live I get a 2TB box with latest intel xeon and 16GB of RAM with a unmetered GB uplink for 30 bucks.
So yeah to me this is kinda expensive for a vps.
It depends heavily where these VPSs are located, when comparing to major providers, he's not far off.
I know of a few places w/ cheap dedi's (such as a few Kansas providers), where are you getting your boxes from?
Europe.
You able to provide any company names?
Hetzner is a good start for affordable boxes.
Best prices is when they hold their "auctions"
You can get 8TB - 32GB RAM - i7 6700 for 40€
Should all be Gbps
