Crawfish traps

So, I'm inspired to go crawfishing after reading the question about zip ties. I don't have much storage for the traps, so I've been looking at these.

Amazon.com: Eagle Claw Minnow Trap (9 x 16-1/2-Inch): Sports & Outdoors



$10 a pop. I could put out 5 and catch pretty decent I would think. Anyone have experience with these types of traps?
