I second the Dive Rite fins, they're nice. The only drawbacks:
I think Dive Rite is redesigning the fin or something right now, so you may be able to find a good deal on the current models.
- They look all nice and shiny when you get them but after the first day you take them into a cave they'll look ten years old
- The rubber section can rip, I know a couple friends whose fins got destroyed that way. They're durable and last a while, but not forever like your Jet Fins have.
Thanks for the heads-up! I talked with Dive Rite and the monoprene version of their fins is at least 30 days out, but I found a new pair of the "old" version with spring straps for $100 shipped andchose to go that route.
