LTB: Used pit with standards

[Greero]

We have a nice pit where I practice, but I am so competitive that I feel I need a pit at home to really get in the time I want vaulting. I have a pretty limited budget so I am fine with any used pit as long as it has everything I need and is less < $500. I realize that is really cheap for pits, but i have seen some go for a couple hundred recently and I am just trying to get an idea of what I can get.

Also, i am looking to buy a cheap copy of B2B2. Thanks.
