So I had a 200 slot server for about a month, and here's my review.
Obviously the price was good. I had some issues with setup, but they added an extra day because of the time lost to setup errors.
First event hosted on it was ok, around 120 players, average pings of 65-70ms. Not bad.
Second event was much the same.
I saw some issues in the third event, however. We had around 160 players and pings averaged around 90-120ms, with the chat constantly duplicating itself.
Other stuff: Control panel was standard TCAdmin, solid enough. Client area was a bit tough to navigate, but not too bad overall. I submitted 1 support ticket and the response time was ~13 hours.
All in all, not bad if you need cheap. I can't knock it for the price it's at, but I'm curious to see a 250 slot server in action.
