First things first Guji, if you live in a second floor apartment, is there a site for the dish? it needs to face SSE and have a clear view in that direction.
It is not rocket science to instal a dish, but a difficult location can make the job a chore, so you may wish to use a local installer.
Whichever package you go for is entirely down to you, the Sky route will work if you are able to organise the phonecalls. The analogue route is easy to organise, but relies on RTL continuing to show the GPs. It shouldn't be difficult to get the relevent setup for Canal Digital or Premier World in Switzerland, you may even get a subsidised installation.
