Timor monitor questions

[Zosime]

I was thinking about getting a timor monitor i did a little reading on it and it seems like a better idea to get one of these than a savannah monitor. So what i was wondering How big should the enclsoure be? What should the basking and humidity temps be, And what should i use for substrate? Also How is their temperment will i be able to hold it or is it going to be super skittish what should i look forword to. I wont get it for awhile so im going to build the enclsoure first so id also like to get some enclsoure ideas.If there are any other monitors out there that stay kind medium and are like 200$ and under i will be willing to learn a bit about it. Im really looking forword to getting a monitor and id like to get all the help i can get.
Thanks for reading..
