Making a 3D DNA model

Hi, I was thinking about trying to make one of those 3D DNA models you see in schools, showing all the atoms in the molecules joined together and climbing up in that beautiful double helix shape.
Trouble is, I don't have the money to spend on one of those several-hundred-dollar kits, and I can't figure out exactly how a single nucleotide should look, let alone how to make several dozen nucleotides and joining them all together.
I've searched google without much success, so any pointers/helpful guide images would be very much appreciated. Thanks
