Pumping

Gayle
So my baby is due 10th December and recently I've been thinking about feeding etc. 
When he/she is born I would like to breast feed if all goes well.
However, I've also been thinking about pumping as an option for a few reasons like I know my husband wants to feed the baby and I think it will help while out and about.
I've read a few reviews with people saying electric pumping is painful but manual not at all. 
Please can I have people's opinions on this ?  Have you done it yourself and how did you find it? Did you feel it was a waste of money or the best thing you could have done? 
I can see benefits from it and the only negative I can see is that if I don't get on with it it's a waste of money. 
Thanks... :)
