Thinking about going on the insulin pump...again

I've been on the pump before, but switched to insulin injections.  They're such a pain in the butt now, and I'm thinking about switching to the pump again.  I've talked to my doctor about it and she said it's a good idea, and eventually I could switch to the Omnipod.  I wanted to know other diabetics suggestions and opinions on switching back and about the Omnipod.  Did you guys see a difference in your blood sugar numbers? Did any of you girls gain weight since starting the pump? And how many of you are on the Omnipod and enjoy it?

Thankyou in advanced for all your suggestions/opinions. :)
