Curious for opinions on CelebzDirect

My gut reaction says don't mess with this based on some threads I've seen about this company's game-used stuff, but:

1) The ridiculously generic COA aside, the signature looks correct
2) Knoblauch wasn't a huge signer, so it's difficult to find signed bats, with good first person authentication (MLB, Tristar, Steiner, etc.), at a good price
3) Knoblauch gives a signed bat to Andruw Jones, who then consigns his personal collection to this company. Kind of a "who would make this up" scenario, especially with someone in as low demand as Knoblauch.

If I was to buy, this is textbook "buy the auto, not the authenticator." Just curious if anyone has dealt with this company before, or has any personal opinions on what's being advertised here. Honest opinions appreciated, you won't offend me, that's why I'm asking.
