Mine is an old Penrose purchased second hand for £40
It's brilliant best 40 notes I have spent. Very easy to push no bother over rough ground, and just works from start to finish just go for it mate.
Fantastic bit of kit for fishing rivers and carting you gear from A to B . I sit on a cushion when on the bank its as light as a feather to push.
My back has gone too. Just bought the lugger as it looks like the best 4 wheel option available. My Preston 2 wheel was trash from the start. I welded it in many places to repair the (before the days of transporting everything) cracks and breaks. IMO stay away from the hybrid trolley/platform. The building, breaking down and setting up from car to peg and visa versa everytime may drive you nuts. Plus the little cushion you get ain't comfy
