I just picked up an ARB 50qt (47l) for ~$760 which I thought was pretty good. ARB offered a free ~$100+ transit bag this month also, so i have that coming to me.
Don't let the plastic bother you, get a transit bag and then it looks great. I like the plastic because it saves on weight. The inside cabinet is metal anyway.
The decision for me was pretty easy, as I want the controls on the end/front and I prefer the lid on the ARB. A side opening lid, or one that isn't easy to pop off, doesn't work for me. I also like that its not finicky latches, multiple latches or something like that. It is easy for my kids to get into and one handed.
Pretty much any fridge is going to be fantastic though. I look forward to using ours on some long trips.
