I have a plastic crate by petmate and a wire crate by precision pet products. I don't remember where I got the plastic one but the wire one is from Petco. It's black, made of metal. Nebo was able to escape from it a couple of times but I fixed that (put metal snaps...like dog leash snaps...on all the connecting parts since it's a crate that is made to come apart). Since that it has been fine, it's a bit heavy but I haven't lifted any others to compare so I don't know if it's heavier/less heavy than others.
