I'm sure that the zippers will last a long time if they are not misstreated. I remember testing zippers on tackle boxes at Wal-Mart the other day. I was trying to zip a cover closed on some other brand and I broke the zipper. How did I do it? Answer: I didn't lift the zipper up out of the way of the corner of one of the plastic boxes and therefore forced the zipper to go around too small of a bend radiius. So, if I would have taken my time and watched what I was doing, it would have been just fine.
I bought the 1200 model at Wal-Mart for $39.95 last night. Besides all my tackle, it can also hold rain suits, a tube tent, survival gear, and "The Extractor" Snake Bite Kit.
P.S. If you go do a google search on the "ten essentials", you will find a list of the recommended minimum amount of survival gear. To mention anymore about it at this point would be going off the subject, so I won't go there.
