Ordered one of the new Disc Gators. Price was kind of steep ($50 for the two pole version with shipping) - but knowing how many times I've used my golden retriever, they pay for themselves pretty quickly. More often than not it helps out someone else in your group.
Looks like it could be a hassle to carry around, but I used to carry around a modified golf ball retriever which was similar, just missing the clamp, at Vista del Camino where there's lots of water and discs are generally retrievable (not as much the case in Iowa). Since I don't have a backpack style bag, I'll have to get inventive on carrying it (it comes with a mesh bag with clips, for that purpose).
The golden retriever will probably still be necessary for some situations like when I land in middle of Duck Creek. But I always hate unwinding (and re-wrapping) the whole golden retriever for short retrievals, and can definitely waste some time casting that thing out. You could wrap the cord around something other than the retriever, that way you don't have to unwrap the whole cord. But I don't. I should.
I'll try to remember to post feedback once I use it.
