I know what you mean, my first twin pram cost me $1600 dollars, and I have two strollers as well. lol but I sold my first pram on ebay and made enough to buy the one in front of the other pram.
I am sorry but I like those torso harnesses. For my piece of mind I find them much safer for my girls and for us when we take them out and let them walk. There are wrist ones out there but I was concerned that because my girls pull alot when they walk that they would hurt their wrists if they constantly pulled on them and I was also worried about other people not seeing them and trying to walk in between us, or the girls walking aroung something and getting tangled because it was around their wrists. But that is just my opinion and I do understand others feel differently, but my girls like wearing them and we do have them very loose on them and hold the leads on them from behind so they feel independent walking in front of us. I found both types were available at Big W and Target stores.
