Trying to find indestructible dog crate

Hi all! I am looking for a serious dog crate that can survive a super escape artist / massive destructor 60lb shepherd mix that'd not going to break the bank. I'd love to hear any suggestions you may have!

edit: I'm also looking for something that's at least somewhat good-looking!

Details below for all who are interested! :

I have a super escape-artist on my hands who keeps destroying and escaping his crate. The classic frisco fold and carry won't do as he has literally bent the metal walls with his teeth and by dragging fabric (blankets, curtains, CARPET) through the openings in the side. Then, I ended up with a fancy wooden crate with less openings in the sides, bottom, and ceiling, that he ended up breaking apart within like 45 minutes of being inside. I've gone through 4 crates in the 2 years I've had him and am hoping for a final solution.

It's not separation anxiety since he's fine to hang out while outside of the crate when I leave him home alone. I think he just has a huge aversion to being locked up. That being said, I prefer to have him contained when I have guests since he's uncomfortable with strangers in the house.
