A push trolley is a better option than a pull trolley. It is much better for your back.
Depends how much you have to spend. I have a Powakaddy. The twinline 3 can be found online for under £90. and is a great trolley. you can also add an umbrella holder
When looking also saw the clic gear and the new Stewart Golf Z1. Looked a great trolley but like the Clicgear is £179.
