I've got the basic one for £69 - its great.

It currently controls:
Projector
Drop down screen
TV
Amp
Xbox One
HTPC
Virgin Media
It's amazing, I press a button and I'll get the TV turn on and change inputs, amp turn on and switch input to whatever is preset. virgin media box turn on etc...
Are they pretty easy to set up?
