experiences with elitek9 collapsible crates - Page 1

i'm in the market for a couple new collapsible crates and the only ones fitting the size requirements are east coast crates' fc-5.5, http://goo.gl/o196Ac, and the elitek9's, http://goo.gl/Vo0k1V . i know and like the ecc's but since the elitek9's are a heck of a lot cheaper, my wallet wants me to give the elitek9's a shot. hence, i'm looking for real-world user experiences with the elitek9 collapsible/folding crates. since air travel is my most important use case for the folding crates, i especially would like to hear from folks who have done a bunch of flights with the elitek9 crates. much obliged.

Try these. I haven't tried them, but they look similar. I use Ray Allen for leashes, etc.

I dont have first hand experience on these crates though. Price is $699.99 plus $35 shipping. I have dealt with this company and I like their other products.

I was looking for something else and came across this
