We have 2, heavy duty is the Joie Chrome dlx. Basic but good we went for it due to the easy travel system compatibility with the Joie igemm car seat. There are far better buggies about but this suited our needs.
More recently we got the ultra compact poxkit+ which folds tiny and is very light. This is primarily to have in the Car as the Joie is very large. As expected very light and a bit flimsy but no complaints so far.
