I’m curious what price they would agree to pay?
You better sit down for this...
They would probably want to pay as much as 4 or 5 hundred!!! Almost everyone here can attest to attention their cabinets get. In my house, it always follows a series of steps:
Step 1: Bewilderment (Wow! I didn't know people could make something like this)
Step 4: Nostalgia (I remember all these games and the good times I had playing them)
Step 3: Desire (I want one of these)
Step 4: Curiousity (Can you make me one?)
Step 5: Balls
Now... I say step 5 is balls because people have the balls to want you to make them one for 3-5 times less than it actually costs. It seems the amount friends and family are willing to pay is in the $300 - $400 range. You stand more luck selling it to a complete stranger - who might be more willing to pay the proper price. The proper price is subjective. Someone like Spacies knocks these cabinets out quickly and has really reduced the amount of labor needed to build. If you only plan on building a few cabinets you better have fun building it because your labor will most likely go cheap!
The main thing that would suck about building someone else a cabinet would be dealing with the support and building a cabinet that is completely idiot proof.
Auction is your best bet, but that can backfire too. I sold my driving arcade and it went for a fraction of what I think it's worth.
