Hafele quit making them a few years ago. Two years ago Jet had one that looked like the Hafele, and I tried to order one, but they refused the order and said they no longer carried them.
I finally ordered the ShopCart, from Adapa. Wouldn't you know, not long after it arrived there was a Hafele on CL. I bought it too, and kept them both for a year or so, when I sold the Hafele to a member here.
The Hafele is a great unit, looks like a copy of the ShopCart. Nice and heavy, with good wheels. The only difference between the two is that the ShopCart has an 'X' type cross brace on each side that goes up and down with the top, making it capable of heavier loads when raised to the max. I have put half a dozen sheets of ply on each one, and in practical use, it didn't seem to make any difference. I am sure the ShopCart would carry more weight, and is probably better in a commercial situation, but for home use, if you can find a Hafele at a good price.....grab it.
