I've got Electrokraft Synth Drums, NESK-1, and Vodavox. Any interest in these three garage-y type carts? (picture attached)

Update #11
I'm looking for the screw variants I don't have. SE is there, but I don't even have a 3 screw copy, so I doubt that one is in my price range. I will pay you a premium for your cart, unless it's really, really, REALLy beat-up, and even then I'll still probably pay you a premium, just not as much. These are games with known copy(ies) out there that I still need:

Adventures of Bayou Billy, The (5 Screw)
Base Wars - Cyber Stadium Series! (5 Screw)
Castlevania II (5 Screw)
Castlevania III(5 Screw)
Contra! (5 Screw)
Defender of the Crown (5 Screw)
Jackal (5 Screw)
Metal Gear (5 Screw)
Q*Bert (5 Screw)
R.C. Pro Am (5 Screw)
Rollergames (5 Screw)
Silent Service (5 Screw)
Skate or Die (5 Screw)
Ski or Die! (5 Screw)
Snake's Revenge (5 Screw)
Stadium Events (5 Screw)
Tiny Toon Adventures (5 Screw)
Top Gun: The Second Mission (5 Screw)
Top Gun 2 (5 Screw)

These guys haven't been found yet, but I hold out hope:
Batman Returns (5 Screw)
Blades of Steel (5 Screw)
Bucky O'Hare (5 Screw)
Contra Force (5 Screw)
Jack Nicklaus' Greatest 18 Holes of Major Championship Golf (5 Screw)
Jackal (5 Screw)
King's Quest V (5 Screw)
Laser Invasion (5 Screw)
Lone Ranger, The (5 Screw)
Mission: Impossible (5 Screw)
Monster in My Pocket (5 Screw)
NASCAR Challenge, Bill Elliot's (5 Screw)
Nightshade (5 Screw)
Pirates! (5 Screw)
Star Trek 25th Anniversary (5 Screw)
Rush'n Attack (5 Screw)
Tiny Toon Adventures 2 - Trouble in Wackyland (5 Screw)
Tiny Toon Adventures Cartoon Workshop (5 Screw)
Zen - Intergalactic Ninja (5 Screw)

Silent Service is honestly on somebodies WTB list. Make it so!

Haha, glad you said something. I actually have that one and forgot to delete it when making that list. Cleaned it up.

EDIT: For the record, I had that game as a kid and played the crap out of it. I remember enjoying it.
 

Updated for my SS. One or two of the items I'd gotten recently.

Knocked off same major players this past month for the Aftermarket Collection. Been looking for all three for years.

Flashboy (1st Release)
Mobile Suit Gundam Z (Gold)
WWE Jake the Snake Edition

Adding the Sweet Home Capcom proof of concept CIB from Timewalk to the list. That and Mario Kart R are the only TW releases I don't have. And yes, I know those are both "prototypes" that weren't for sale.

Crossed off some screw variants I'd picked up. Thanks, Kirk, for giving me Contra for Xmas. DivingNinja knows how deep Contra goes in my veins.
