how do you create your drum/ bass sections?

I'm peeking into the world of digital recording and have downloaded trial versions of Guitar Tracks and Kristal, as well as Band in a box. I was wondering how you guys build your drum and bass sections? I don't have a midi keyboard so I'm looking at programs like band in a box to create sections to record and then use sound fonts to make it sound more real (sounds like a lot of work). I see that guitar tracks has drum and bass looping, how does that work? Can anyone give me any examples of what the looping sounds like? What are you guys using other than real instruments?
