Servos?

Hi, so me and a friend are building our first reprap (the 1x2), and I know that we can do all the mechanics brilliantly.
However, I am wondering if anyone has used servos. I am just more comfortable with servos as compared to steppers.
My question is, how can the software be changed to use servos?

I can't see any reason why servos would be any worse than steppers except for the software issue.
We want to drive the servos streight off the Sanguino board (of course with an external ps).

Any Ideas or working examples?

... you can use servos like steppers if the servo-driver has DIR and CLK inputs, otherwise you need high resolution encoders and have to rewrite the software to read the encoders as feedback and change all the code where speeds and acceleration is set ... a really big piece of work ...
