I'm not sure of the names of the types of hamsters, so bear with me. I've had four brown hamsters - two as a teen and two as an adult. I don't ever recall them biting. Nor did they breed - thankfully. They lived about two years or so.
Two months or so ago we bought a black teddy bear hamster. The kids had been asking for one (not specifically a teddy bear or black) but the night we found him in a back room pet store in a "yucky situation", my DS (and the rest of us) didn't want to leave him there so we brought him home with us on the spur of the moment. The owner of the pet store told us these hamsters were bred to be friendly and I think he was right. He told us they only nip if they smell food on your hands and that seems to be true so we wash before we hold him (and after, lol).
He is adorable. And friendly. And I can't believe how much he's grown on me in this short a time. We all love the little guy.

His name is Gus (because he reminded us of Cinderella's mouse Gus - in sig, lol).
I did a quick read of his type of hamster and read they like to live alone, so we decided that for now he'll be an "only". We bought a small cage at the pet store that night, but realized as the weeks went on he needed more room, he's big to begin with and has grown.

So I bought
a bigger version of the same cage and it's awesome. Putting it together was tricky, but once we got past that, it was great. I had to buy it online as I couldn't find it in stores. I'd recommend it. (Be careful where you buy it as the price varies from $56 to as high as $139!). It's fairly easy to clean. We vacum it out with the Shop Vac and then wipe down all the structures inside with soap and water without taking it apart. Takes about 20 minutes. My two 12 yr olds do most of the work with a little help and supervision.
He's quite active and happy in his new digs, and we also let him run around the house in his ball for an hour or two each evening which he loves. It is hysterical. When we first put him in the ball, he'd bump into all the furniture and walls. Now he steers the ball - left here, right there, straight ahead, etc.

He's seemed to learn really fast and knows his name and such. Our German Shepherd is enamored of him and watches him for hours. She licks him (gently), follows him around in his ball, and lets him run on her back when we're holding him. We'd all miss him if he was gone.
I have to get some new pics, but here he is.
