I see that ED Horizons is on sale at the moment at both FD and Steam. I only have ED at the moment that I bought in the sale for £9.99. It has been good value but was the most I had spent on a game for many years. The last full price one I bought was Skyrim on release.
I have to admit I am tempted to get Horizons for £19.99.

"What people like and what critics praise are rarely the same thing. 'Critic' is just another one of those unnecessary, overpaid, parasitic jobs that the human race has churned out so that clever slackers won't have to actually get a real job and possibly soil their hands." Sauron
Actually I thought the same but it is kind of intuitive and I had no problems out the gate. A couple times I was too fast and, game mechanic-wise, it's just like getting pulled out of SC - annoying but not fatal.
Just think "Space Shuttle" and you will fit right in and you won't die. May take a few to get real good though especially in high G worlds.
Good investment also. I found it added quite a bit to the game.
