Yes, you are right, I forgot about that wire spacing on that cage. So that one is out of the picture, too.
I actually don't have the bird at the moment, so I don't know what the temperament will be. (It's apparently impossible to find lovebird in Austin, TX!) My previous bird didn't chew on bars either, just used the beak to climb on them, and of course play on the grate.
The closest King's cage that has fold down door was this
King's Cages - Avian and Pet Bird Cages, Supplies, Food, Toys, Perches, Aviaries, Pluck No More
and it's reasonably priced, but it doesn't have 2nd door, I don't like that top that opens ...and I don't need the stand.
Their Cheap, European, and Economy Line Small all seem to be too small for a lovebird.
HQ has almost the same cage

This is probably the third week of my every day cage search. I looked at A&E, Prevue, Super Pet, YML, Blue Ribbon, Hagen Vision, Prtco, Petsmart, Marvelous Pet Supplies, HQ, ... they are all missing something, either door that folds, good latch, horizontal wires, 2nd door, pull out grate, nice top,.... maybe I am being just too picky.
My budget is up to $150. I used to have a regular "economy" style cage, and 11 years it's ready to be retired or used for travel only. Once I saw those cages with thicker wires on the edges, like the blue ribbon one, I kind of fell for them as looking more sturdy and durable. I think I am ready for those "grown up" cages now.

If only I could find one that has all my other requirements!
