Recently purchased a Ruckus AP. This AP allows for 25 SSIDs. Totally different OS than the Ubiquiti devices.
It has a self healing AP to client relationship and will adjust automagically.

Purchased an indoor AP and POE mounted it in a closet in the center of the home. Works fine here on the second floor, main floor and basement.
It is a bit more expensive than the Ubiquiti APs. That said there are many on Ebay sold as new old stock these days.
Here are some pictures of their outdoor stuff which is used all over the country for opensector AP stuff (public internet).
