Not to be a downer, but I think you're a bit optimistic on the price. If it were a factory machine with factory or vendor support your price wouldn't be out of the question. However in this case there will likely be no warranty beyond the sale, and no support should the new owner have trouble with either the software or hardware.
Lack of support at least for the first year will have an impact on what people are willing to pay. Most will look at it as a used CNC machine and be willing to pay accordingly. The mechanical components may last forever, however the electronic components are a different story. Even though they are now new they will have a limited number of years before they are considered obsolete and will no longer be available. In most cases these types of electronics are supported for a maximum of 5 years. Even then they will not be replaced under any warranty. That means a potential added expense beyond the buyers initial purchase price. After the 5 year period if a part fails it's likely the machine will need to be retrofitted with different electronics.
Using eBay and Craigslist as a guides there are several nearly new Bridgeports with EZ Trak and Pro Trak CNC conversions. These machines have a new list price between $34,000.00 to $36,000.00. At only a year or two old they are going for less than 1/3 that price. Most on eBay and Craigslist have asking prices north of $12,000.00, but actual selling prices between $6,000.00 and $10,000.00. If the same scenario holds true for your machine you can realistically expect to get a return of 1/2 to 1/3 of the initial investment.
