They are a lot of fun. So much easier to escape from than you would think. Even if escape is not your thing they can teach a lot about presentation since the most important part is making it look harder than it is.
Yah, I've been kinda reading a bit about it and it appears that once you're "set" they are quite a bit easier to get out of than what most people would think.
I don't know when I'll end up getting one...I have way too much stuff that I want to get and it's getting into spring so I need to think about getting some things going for yard work and doing some athletics outside. But hopefully I'll be able to order one in the next couple of months.
