Easy, no! Absolutely not. You become a slave to the green giant. It's worth it if you don't mind having your life run by a lizard though. Iguanas can be every bit as sweet as bearded dragons and are far more intelligent. Each one has its own personality and behavior patterns.
BARE MINIMUM enclosure size for an adult is 6 feet tall by 4 wide by 3 deep and that is only appropriate for an adult that is less than 4 feet long, meaning it's had health issues from improper care and is stunted. It does NOT mean an adult with a stub tail as they are still highly active and need lots of climbing room. 8x6x6 is bare minimum size for a 6 footer. Frankly, if you don't have a room you are willing to spare for the iguana it's not the best pet for you.
Yes, I've been bitten and their bites are significant. Igs have multiple rows of razor-sharp teeth rather like a shark. My own Gizmo just gave me a tiny bite when I was rubbing her head after making a spinach salad for my lunch. She tongue-flicked me multiple times and then tried a test bite.
She didn't even bite down, as soon as she realized it was my thumb and not food she let go but 2 weeks later I still have a perfect imprint of 2 rows of her teeth and not much cuticle anymore.
I've been bitten countless times by igs brought into the vet hospital for surgery and many of them needed stitches and several rounds of antibiotic injections. I'm not saying this to scare you off, but a prospective iguana owner needs to be prepared. Sometimes even the sweetest ig might get sudden periods of aggression, especially males during breeding season.
If you can get your hands on a copy of James Hatfield's
Green Iguana: The Ultimate Owner's Manual that book was specifically written to let prospective iguana owners know what they might be getting into, and is a highly entertaining as well as informative read. Here's a link to a couple of care sheets written by iguana owners I know with their own personal insights:
