Bought this for $80 at REI and have used it a handful of times. It has held up well so far, and it really does weigh less than 3 pounds. Plus it fits in the forward hatch on my Caribou-S without being taken apart (I do have to work it in by rotating it around).
The downside is the hard wheels transmit every bump straight into my arm as I'm carrying the other end. This is especially fun on those concrete boat ramps that're made of concrete planks with gaps between the planks. It does plow in soft sand somewhat, but not as badly as I expected. Unless you have to go a long way in the sand or you have an especially heavy kayak, it should be good enough.
And the price was right, certainly by comparison to other products in this category.
