There are bond LEs available at MSRP or close to it right now. With the exception of Godzilla, recent LEs aren't selling for a ton over MSRP right now.

If you have 14,000 to sit on for 12 to 18 months, nobody would recommend the best way to make money off that is to flip pinball machines
Finally, there's been a handful of reports of people receiving bond LEs where the box is totally fine, but they open up the box and it's damaged. Not sure what your recourse will be if you wait 12 to 18 months for your buyer to open and find out it's damaged.
