Okay, I will get you a horse cheat.
The best horse in the game is Shadowmere. You get it from a quest, so use this code at your own risk:
player.additem 00032bf4 1
There's the Bruma horse, much less risky:
player.additem 0004de91 1
Sorry to correct you Kole_Skepar but i dont think you have the right code for the horses, i think that the code you want is Player.PlaceAtMe then the horse code, you did get the horse ID number right though
