I agree but most newbs will have a hard time finding a House snake. They are not very common in the trade yet.
The easiest snake to buy and own is the Corn snake. They are by far the easiest ones to work with and the more appealing due to the color morphs. You can get a corn from a breeder ranging from $15-$100 (and up) depending on the morph.
The best cage to get is a 20 gallon long Critter cage if you want something to display your snake in. You will need a Under the Tank heat pad and remember snakes do not need light. They are fed once a week. And I recommend feeding your snake Frozened thaw mice. 99.9% of the snakes will eat these readily, heck, even my wild caught snakes prefer frozen thawed rodents.
I keep mine in rack systems and tubs. They are cheaper and easier to clean.
Now as you stated you want a snake to sit and hold and will not mind being held. Well, that isnt going to be easy. I have over 70 snakes in my collection and only 1 and I mean 1 snake will sit and be held. Most snakes will sit there for a bit and then want to squirm away after they warmed up on your body heat. I just wanted to give you that bit of info. Not all snakes will settle down for you and you may get bored with it. I have seen this happen once to many times. I have rescued many reptiles from the humane society by being callled to pick them up. It got old really fast seeing the amount of unwanted animals.
So, I want you to think about it as well, are you ready to keep a pet for the next 20 years? Snakes live a long time, a lot longer than a cat or a dog.
Since this isnt really a snake forum but we do have members here who do keep them but I do not think its bad form to post links to a snake forum to help you ask your questions and also you can search the threads to get more information.

This forum was created and still owned by one of the top names in the corn snake hobby. He has created and discovered many of the color morphs.
I also recommend a book the Corn snake manual by Kathy Love. You can pick that up at any pet shop or going to her personal site
