Yeah hack labs usually are pretty complicated.. I've known a handful of people who 'planned' on trying to set one up, but it never happens. And with that, live networking hack labs are hard to come across. The best experience is the real experience, amirite? Set up a vulnerable server and do work my friend. Hack into your own wifi, DoS your own system, MiTM your own traffic. No substitute like the real thing. But of course, you'll have to get the knowhow from other forums and articles around the interwebz. But we already do that anyway.
For those about to hack, I salute you.
