£20 a month would get you a decent server but if you want freeze free sky HD then expect to pay that on its own!
Most servers have too many people wanting SKY HD and after tea time week nights it gets jammed with too many people and you get freezing...which is really really annoying!!
in a year ive managed 2 find 2 servers which where 99% of the day freeze freeze and any freezes would be 1 maybe 2 and thats it
1 guy dissapeared after 6 months and the others great but far too expensive!!
