I need your help ladies!!

Chiquitta
So I've been looking around for strollers/ traveling systems. I've boiled it down to one but it's a bit on the expensive side and I'm not sure my fiancé would go for it. So, I would like to know if there are any other types close to the one I have picked that maybe less expensive? Or if I can get the one I want from somewhere else a little cheaper...
I chose this stroller because I have a 6 month old and I'm currently pregnant (3 months) so I don't know if my 6 month will be walking by the time the new baby comes!
