I got one for my last birthday. It's my favorite machine too.
Agreed, machine pullovers really hit the lats while taking the arms out of it. They're a good first exercise to get warmed up and going.
I usually like to finish up with them. I especially like to on heavy back days. My favorite back routine is doing deads, barbell rows, t-bar rows, and then finish up raping my back by pyramiding four sets (to failure) on the pullover machine with a drop set after the fourth. As good as it gets.
