Travel System!!! Help! Choices!

Victoria
I don't want to spend the earth but I want something comfortable for my baby but good quality that will last if we have more babies again. The Mothercare lady said one had better suspension but I could see no suspension on the thing just bigger wheels on the one she suggested. Really lost as we live with lots of hills and looking to go walking a lot so bouncy would be good!
Any suggestions please! UK available please!
