It looks like my Congorilla cab. I picked it up for $35.
Congorilla cabs actually have Crazy Kong boards installed, one big benefit of your cab is the jump button on the right. My cab only has it on the left.
Appears to be a Crazy Kong upright which is a DK bootleg. I have a Crazy Kong mini. I've never seen that marquee before so I don't know if that's someone's homemade creation or a bootleg marquee to go along with the game.
If it works 100% I'd say $100-$200. Knock-offs seem to go cheap, at least where I live they do. I paid $50 for my working Crazy Kong mini.
