I think I saw the Mr. Perfect doc on WWE 24/7 & it's fantastic. It was like he could do no wrong in anything he did.
I got the WWE Stars of the 90s at Walmart for $5.
Don't remember where but I bought "The Legends Collection" that came in a Tin box and it had the Pillman, Jake The Snake & Bret Hart documentaries and I know I didn't pay more than $10 for it. That was my best find ever. I'd look for that if you get a decent price.
Here it is. New $9.99 + S&H - Used $6.44
