Arcade machine conundrum.

So, a few years ago I bought an arcade machine called Kick from Shawn at Game Repair. My first, and only arcade machine at this point. It's classic and it's the only one I ever wanted except Egg-stravaganza...but Shawn said he'd buy it back for what I paid for it, and not only could I use the extra cash but I hardly ever play it, so he'd get more out of it than me...

So, should I sell it?
