You can get free test lines, usually 24hr if you
want to try it first.
Then when you have found one your happy with
you pay them a subscription, 1 week,1 month 3 months, etc
They all usually knock a bit off, the longer you sub with them.
Best not go too cheap, what you are after is a stable server
with minimal, glitching.
You will see "100% glitch free" everywhere, but in reality, I have never
found one who lives up to that.
