Satellite tv

hi I have just lost all my tv channels don't know if anyone else has had the same problem, I am still using the old system with a mesh disk picking up channels of the old telmicro broadcast which went off air then about six months later some channels came back.
Was looking at getting a new system but still unsure best way to go? Any ideas would be a help looking for getting all free Uk channels with a system that will still be going in 2 years time not like some I hear about which get switched of after a few months when your paid all your money.
Heard you can get system for £ 195 euro, what size dish is this system got, know it's best to get a 1.9 m dish but they are very expensive !! Anyone got one for sale?? Message me thanks
