Money VERY well spent. I highly suggest picking one up
A strong mixer with a dough hook would have been a better investment, much more versatile in the kitchen, not just for a variety of doughs, but anything else that needs mixing/whipping etc.
I don't really see why you're so taken aback.
1) It's easy. Just throw the ingredients in and turn it on.
2) It frees up the oven (and the mixer) for other things, if I'm cooking a big meal
3) It was $10!
