Slow Cooker Help!

May • Very Happily Married. Wishing for that little one to complete us
This may seem trivial but cooking to me is no trivial matter! Lol. I need to buy a slow cooker (crock pot). 
I want to cook pulled pork roasts etc in it so it needs to be a decent size. I have an older one that doesn't cook the food evenly and it's just too darn hot to touch on the outside its dangerous while it's on.
Any of you have a slow cooker they would recommend? I'm forever in your debt if I can find a beauty.
