Drum Machine or somthing?

I want to create songs by myself with like a drum machine that I can pump out of my amp or somthing, how much do these cost? and are they worth it if ur into music that nobody else wants to play besides you, like instrumental, just hard good guitar soloing

I use a little zoom drumcomputer for recording and rehearsel purpose. It has also a base in it.
There are a lot of possibilities but i use only the programmed loops. You can program it from measure to measure but it takes a while. So i'm a little bit lazy and rather play my guitar than pushing all day at the little knots. But if you take the time its possible to compose your own song.
I don't now the price anymore but it is not to expensive.
For rehearsel it's more fun then a metronome.
