I’d guess 99% of freesat “customers” had sky and realised they could get the same channels for free. If you dont have sky currently you can install a sky dish for maybe £40 diy. Whatever you do get Freesat+ (record, pause, fast forward tv). Thouroughly recommended.
DIY a dish is easyish and a mega rewarding DIY project.
Freesat+ : Kids record whatever, missus watches whatever, all the good stuff is up to you. And freesat does iplayer etc (if you got a network connection nearby).
#Edit – the £40 is for the dish diy. You’ll need a freesat/freesat+ box on top of that: anything from £40 to £300 depending on what you want. Google Humax Direct for ex-demo boxes with superb backup and warranty – also a Which Mag recommended best buy. So top end – HD with record / pause etc – probably £300 ish.
