Now that I own one each of the Stauffer and Sundance pollen traps, I find them to be almost identical in all respects except one. That is that the cone bee escapes at the entrance of the trap which allow the bees to exit the hive without having to go back through the pollen collection grid are of different materials. The bee escapes in the Stauffer trap are made of plastic while those of the Sundance trap are made of relatively heavy gauge stainless steel screen wire. The wire bee escapes are more heavy duty (less fragile) than the plastic ones and should last longer. Because they are screen, they should also provide slightly more ventilation. The differences are not big, but I now have to agree that the Sundance trap seems to be the most ruggedly built of the best materials. Besides the bee escapes, all the other materials seemed to me to be almost identical, as is the design. I would think that excellent results should be obtained using either trap. I look forward to using both of them this season. If you want "the best" then the Sundance trap (to me) has a slight edge and I would therefore consider it marginally the better of the two. I guess I may find out through time whether or not I am right. Layne Westover, College Station, Texas, U.S.A.
