When I had the twins we hired from Baby For Hire 2 x Babylove Snap N Go.

I found that one wasn't as heavy 'empty' as the others available so factoring in 2 x baby weight as well. They were the best thing for my boys as they were born in May, so didn't have to worry about standing in the rain and cold strapping them into carseats.

But for DD we didn't worry about using a capsule as we didn't have a compatible pram and she was born in October so it was easy to just carry her to the car and strap her into the carseat.

Seeing you will have to take bub out of a capsule to put into a pram or carrier when out and about, I personally wouldn't worry about hiring a capsule especially if you already have a carseat that is from birth that can be installed rearwards facing.
