I've sold a lot of stuff on eBay over the years, and I can tell you for a fact that a well written auction is imperative if you want to maximize your profits. Since you are not selling the item face-to-face, you need to describe it in as much detail as possible. You also want to say things that will comfort potential buyers, as well as set your machine apart from the pack. For example, if I ever sell my Tommy, the auction would go something like this:
"You are bidding on an excellent example of a Data East Tommy pinball machine (1994). This machine is from my private collection (my home is smoke-free), and I have owned it for the last three years. It's honestly one of the nicest Tommys I have ever seen. I take excellent care of all my games, and this one is no exception. The playfield has been cleaned and waxed on a regular basis, and the balls have been changed out at least twice a year. There are no broken plastics, and the boards are all in excellent condition. There are a few minor blemishes on the cabinet and head, but overall the exterior is in great shape. Most importantly, there is no flipper button wear, a problem that is very common on these games. It also has the original Silver Ball topper.
The game was really nice when I got it, but I took it to the next level. Here is a list of what I did to it:
* The speakers in the backbox and cabinet have been upgraded with Pinball Pro speakers and a subwoofer.
* LED's have been tastefully installed throughout the entire game, including the backbox. I left in a few regular flashers where I thought the LED's were too overpowering.
* All of the plastics have been replaced with new ones. A full set of plastic protectors has been installed as well.
* The original auto-launch assembly has been replaced with a modern Stern one. This makes a HUGE difference in reliability.
* The original translite has been replaced by one that was hand signed by Roger Daltrey.
* The original Blinder Servo PCB has been replaced with a newer, better designed board from Pinnovations. This board is no longer made, and nearly impossible to find. Here is a link to an article about it:

* A remote battery holder has been installed to eliminate the possibility of acid damage to the boards.
The playfield is in phenomenal shape. The only wear at all is by the VUK and scoop, and both of these spots have Cliffy protectors installed which completely hide the wear. The game plays perfectly, and there are no errors whatsoever. The blinders function perfectly as well. Here is a video I recently took of me playing it:
As you can see, it's a gorgeous game, and you'll be hard pressed to find a nicer one anywhere. I honestly hate to sell it, but I am out of space and something has to go. If you have any questions whatsoever, please don't hesitate to contact me.
Good luck with the bidding!"
Now this is the type of auction that grabs someone's attention and makes them want to buy your machine.
