Signed midnights vinyl ???

Okay so I know there’s probably a thousand posts on this already but I’m just starting my collection and I keep missing the signed ttpd cd/vinyls so I’ve set my sights on midnights.

How much is too much for a resale?

Where are the best places to go to find them?

How do I know the signature is real?

I really want a signed vinyl (I only have the mahogany vinyl) but the CD would be great too.

I guess I’m just not trying to break the bank.

Thanks in advance 🫶🏻🫶🏻
