Well, are you alright with all insects/arachnids? I would suggest a tarantula of some form. There are a fair amount of them around, they aren't too pricey, and there its allot of information available on care.
Your going to need substrate, I've seen allot of people use vermiculite, with coconut fiber ontop of that. Something for the spider to hide in. I would add something it can climb on. If you have a room in the 80's, you don't really need heat, but you may depending on the room temperatures.
