I'm thinking of getting my flatmate a cheap satellite receiver for her birthday... She has a very old Sky dish, I don't think it's been used for a long time, I'm talking last century... Will she need a new LNB? If so, how easy would it be for me to change it out, once I get over the whole looking down from a height issue?
If I had plenty of money I'd be back in my old place with terrestrial reception, so cost is the main issue, just ahead of Fear of Heights...

and then re clipping the new one into place.
