A DB is not really an ideal place to start unless you are willing to put WEEKS of hard work into learning how they work under the bonnet. You dont take one out of the box and get the best out of them in the first couple of nights!
Italian and Polish channels can be found on mainly on a cluster of satelliotes known as the Hotbirds at the orbital slot of 13E. Whilst there are some free ones, most of the interesting stuff is scrambled, so you need to think about subscription costs a well.
You could get 13E & the Sky UK satellites at 28E with one decent static 80cm dish and a bit of clever electronic switching.
