RE: Something small and stable...
Outdoors + Windy + Electric = T-Rex 450
You might be able to get away with a Blade CP Pro. But the T-Rex is a better performer. A good solid Head Hold gyro like the Futaba GY401 makes the tail behave as good as it can be. The CP Pro could be used indoors depending on the size of the room. Both the T-Rex and the CP Pro will damage walls and furniture.
Now, neither of these models are anywhere close to the coax models in terms of stability. You have to fly these models constantly, and there is a steep learning curve. I would highly recommend getting a simulator and putting in a lot of practice time before spooling up any single rotor model.
