I have a Powakaddy Twinline 1 push trolley, very impressed with it.
I've had it for 5 months so not long term yet but it has been used on average twice a week since purchase.
It's strong and very light to push but heavier than normal when folded, but that's explained by the frame build.
The brake on mine isn't much use but I never use it anyway, as my home course is fairly flat.
It doesn't fold up as small as the Twinline 3 or the micro 6000 so if space is an issue you need to bear that in mind.
All in all it's a lot better than the pull trolley I had previously.
Hope this helps a bit.
