I have 2 savvies and they can be really great pets! Our biggest is an escape artist.
So if you get a tank that is long but not very high i would recommend a lid that locks. Ours are still small so most of the time its no prob but if we leave the room with the lid off they are gone
And they eat alot. Our small one went into renal failure a few months ago and the vet put him on some medical dog/cat food and told us to give him electrolites. Our big one has an attitude at times and really doesn't like to be messed with too much, her previous owner mistreated him. But he is much better now with us. I would recommend savannah's but make sure you have the proper lighting/heat for them. And i would also recommend not getting a hatchling. Even thou their bite is not hard it is hard to keep them alive. I had one and it died within a few weeks apparently the whole litter of monitors from that pet store had died
Good luck
