Panthers seem like they may get too big, and seem to be mean? or less friendly? We didnt hold our cham, so I guess thats not really a big issue. Panthers here are like $250 to $300 to special order one, our jacksons was only $75, and I felt the money was better spent on his enclosure than on the cham itself. The veileds are pretty cute but I was afraid if I ended up getting a female that it would get egg bound, and I had at the time wanted to keep my options open for a male and female, separated of course. I know they have live birth but can a jacksons still get egg bound? Dumb question Im sure. If we try again I will be building a 32"X30"X16" screen cage with misting and a lot more plants, Im just having a really hard time with a good drainage system. PS I really like the look of four horned chameleons, not sure if they have another name or how easy they are but so interesting!
Coming from the same sort of isolated location you do, I can appreciate what your limitations will be, so here are some thoughts FWIW (and I also like horns!):
Any cham you get will occasionally need vet care, even if it is just a fecal analysis or a prescription for an antibiotic to treat an infection. Find out what herp-savvy vet support you have and what it will take to get your cham to it. Just know what you'll need to prepare for and have some basic meds on hand.
Your cham will basically live indoors for its whole life, so the climate in your house has got to be dealt with. It will be harder to provide the humidity a montane species will need, especially in winter. To keep my K. fischeri even close to hydrated it took an automated misting system, an ultrasonic humidifier, and careful hand spraying. Plus there's the care of large potted live plants to consider. Montane species will want even more dense cage plants than others. Proper lighting will be key as you can't count on much if any outdoor basking even in summer. Plan to stock up on UV lighting in advance and don't expect the closest pet store to carry what you want. My nearest city is Juneau and there's one small pet supply I use. They do try, and carry a lot, but chances are they won't happen to have the one thing I need.
A variety of properly sized feeder insects will be a challenge unless you rear them yourself. We are talking crix, roaches, superworms, flies, silkworms, waxworms, hornworms or any other type you can think of. All of them will either need to be flown in or shipped through the mail year round. Expensive and takes planning. You'll lose some in transit too. You will need to order and ship their gutloads, any supplement dusts, and other fresh foods too.
Be ready for a power failure...what sort of heat or electric can you get if you end up "off the grid" for a few days. If you have a wood stove as back up heat like I do, that will just suck the moisture out of the air even faster.
I'm not trying to discourage you from ever keeping a cham, just pointing out the realities that you ran in to with your first cham and what you will still face with another.
About the more commonly kept species:
Veileds are not always mean. My first cham was a male veiled and he was fine. Many here have perfectly nice ones. Jax and other montanes are not always docile. They may not try to bite you but they do show their stress in other ways such as extreme shyness. I've had spooky nippy jax, stressy fischeri, and a very surly deremensis. Panthers may be expensive but there are also many high quality, healthy captive bred lines available. Both veiled and panther chams are a bit more forgiving of drier indoor situations under lighting. Jax and other montane species are more sensitive to diet mistakes and over supplementation. They can have trouble with developing ova even though they don't go through egg laying. If there are nutritional problems going on they can still get into trouble expelling unfertilized or undeveloped ova and can die. Jax are prone to temporal gland infections (the little gland at the corners of their mouth) and they can be tough to treat without direct access to a vet. Those four horned (quadricornis) chams are even more "montane" in their needs than jax. We know a lot less about their nutritional needs and very few if any available will be captive bred.
