I recommend the Ashman. We had several plastic ones (seemingly decent ones) that after a couple of seasons of use and high sun exposure have cracked or broken & ended up in a landfill (insert sad face). If you think you'll be wheeling it around and abusing it, spend the money and get something metal (that is weather resistant!) and heavy duty.
Ashman Garden Hose Reel Cart is a really good product. There is a storage basket for quick and easy access to all of your most used tools and accessories, and the garden hose reel cart has a built-in 6ft connection hose for easy hook-up to water supplies.
