Welcome to HC! I think Syrians are the best.. Don't listen to me though, syrian is the only type of hamster I have had so far! But they seem pretty docile if you give them the right handling. This is Scarlet and her cage set-up. I'm gonna get her more toys for Christmas to fill up the empty spaces!
I got her cage from amazon.com and it is the WARE Chew Proof Critter Cage.
Just go on amazon.com and search it. It is a good size cage. 25 inch. You might need to clean it more often because of the hamster pee so it might get rusty.
Her wheel is a 10 inch comfort wheel and she has an igloo and a pumice rock for her teeth. That toy in the corner is a boredom breaker. There are like 4 different kinds. It is 15 centimeters square. She has a cerimac food bowl. You can make your own hamster toys. Just go in the DIY section of the forum
You'll find lots of info. You might even consider a dwarf. Though, you cannot use the WARE cage because the bar spacing is 1/2 inch. Way too big for a dwarf. Here is Scarlet's cage set-up for a little head start on what to do.
